Tunable spin-spin interactions and entanglement of ions in separate controlled potential wells

August 7, 2014
Author(s)
Andrew C. Wilson, Yves Colombe, K. R. Brown, Emanuel H. Knill, Dietrich G. Leibfried, David J. Wineland
Inspired by the ideas of Richard Feynman, 1 David Deutsch, 2 Seth Lloyd 3 and others, researchers in the field of quantum information processing and simulation seek to harness the quantum-mechanical properties of well-controlled laboratory systems to

A Method for Fabricating Conductometric Gas Sensors of Metal Oxide Nanotubes Formed in Porous Aluminum Oxide Membranes

February 2, 2009
Author(s)
Reit Artzi-Gerlitz, Kurt D. Benkstein, David L. Lahr, Joshua L. Hertz, Christopher B. Montgomery, John E. Bonevich, Stephen Semancik, Michael J. Tarlov
We describe a general, simple strategy for fabricating conductometric gas sensors from metal oxide nanotubes formed in nanoporous aluminum oxide membranes. In this approach, the aluminum oxide membrane serves as both a template for growth of the sensing

Covalent Surface Chemistry Gradients for Presenting Bioactive Peptides

October 16, 2008
Author(s)
Matt J. Kipper, Hynda K. Kleinman, Francis W. Wang
The activation of surfaces by covalent attachment of bioactive moieties is an important strategy for improving the performance of biomedical materials. Such techniques have also been used as tools to study cellular responses to particular chemistries of

Nanocrystal-Based Biomimetic System for Quantitative Flow Cytometry

February 6, 2007
Author(s)
Marina Dobrovolskaia, Hyeong G. Kang, Matthew L. Clarke, Anil Patri, Jeeseong Hwang
Flow cytometry has been instrumental in rapid analysis of single cells since the 1970s. One of the common approaches is the immunofluorescence study involving labeling of cells with antibodies conjugated to organic fluorophores. More recently, as the

Ranking Interventions to Improve Inner-City Housing Indoor Air Quality

June 24, 2005
Author(s)
Steven J. Emmerich, Cynthia H. Reed
The U.S. Department of Housing and Urban Development (HUD) has identified a need to improve urban housing conditions to protect children s health through its Healthy Homes Initiative (HHI). One critical area within this program is to address a wide range

Grafting Segments from the Extracellular Surface of CCR5 onto a Bacteriorhodopsin Transmembrane Scaffold Confers HIV-1 Corcceptor Activity

April 1, 2002
Author(s)
N G. Abdulaev, T T. Strassmaier, T Ngo, R W. Chen, H Lueke, D D. Oprian, K D. Ridge
The G-protein coupled receptor CCR5 binds three distinct B-chemokines on the solvent exposed segments of the extracellular surface. This same region of CCr5 also interacts with certain macrophage-tropic strains of HIV-1. To investigate structural features

New Approaches to the Development of Fire-Safe Materials (NISTIR 6465)

February 1, 2000
Author(s)
A B. Morgan, Jeffrey W. Gilman, Marc R. Nyden, C L. Jackson
Thermoplastic polyetherimide-clay nanocomposites were synthesized from 1,3-phenylenediamine and bisphenol A dianhydride using an in situ approach. Two types of organically treated clays were utilized to synthesize these nanocomposites. The two organically

A Policy Perspective on Electronic Commerce

September 1, 1999
Author(s)
E Maxwell, S A. Wakid, J A. Moline
On July 1, 1997, President Clinton issued A Framework for Global Electronic Commerce identifying nine areas in which international agreements would be needed in order to preserve the Internet as a non-regulatory medium.The implementation of global

Algorithm-Supervised Millimeter Wave Indoor Localization using Tiny Neural Networks

January 17, 2025
Author(s)
Anish Shastri, Steve Blandino, Camillo Gentile, Chiehping Lai, Paolo Casari
The quasi-optical propagation of mmw signals has been instrumental in designing high-accuracy localization algorithms. These algorithms either exploit the geometric properties of the mmw signals or are based on an environment's radio footprints, leading to
