Quantification of the Binding Affinity of a Specific Hydroxyapatite Binding Peptide

January 27, 2010
Author(s)
Michael C. Weiger, Jung Jin Park, Marc D. Roy, Christopher M. Stafford, Alamgir Karim, Matthew L. Becker
The genesis of bone and teeth results from highly coordinated processes which involve several cell types, proteins which direct the nucleation and crystallization of inorganic hydroxyapatite (HA). Recent studies have shown that engineered peptide sequences

Comparison Testing Protocol for Firebrand Penetration through Building Vents: Summary of BRI/NIST Full Scale and NIST Reduced Scale Results

January 25, 2010
Author(s)
Samuel L. Manzello, Seul-Hyun Park, John R. Shields, Yoshihiko Hayashi, Sayaka Suzuki
An ASTM task group on vents, organized within Subcommittee E05.14.06, External Fire Exposures, has developed a reduced scale test method (not presently a standard) aimed at evaluating the ability of vents to resist firebrand intrusion into attic and crawl

Linewidth narrowing and Purcell enhancement in photonic crystal cavities on an Er-doped silicon nitride platform

January 25, 2010
Author(s)
Yiyang Gong, Maria Makarova, Selcuk Yerci, Rui Li, Martin Stevens, Burm Baek, Sae Woo Nam, Robert Hadfield, Sander N. Dorenbos, Val Zwiller, Luca Dal Negro, Jelena Vuckovic
Light emission at 1.54 mm from an Er-doped amorphous silicon nitride layer coupled to photonic crystal resonators at cryogenic and room temperatures and under varying optical pump powers has been studied. The results demonstrate that small mode volume

Resistivity Dominated by Surface Scattering in Sub-50 nm Cu Wires

January 25, 2010
Author(s)
Rebekah L. Graham, Glenn Alers, Thomas Mountsier, N. Shamma, S. Dhuey, R. H. Cabrini, Roy H. Geiss, David T. Read, S. Peddeti
The electron scattering mechanisms in sub-50nm copper lines were investigated to understand the extendibility of copper interconnects when the line width or thickness is less than the mean free path. Electron-beam lithography and a dual hardmask approach

Effect of Heat Pump Commissioning Faults on Annual Energy Use

January 24, 2010
Author(s)
Piotr A. Domanski, Hugh Henderson, William V. Payne
The study sought to develop an understanding of the impact of commissioning common faults the energy consumption of an air-to-air heat pump installed in a single-family house. Through annual simulations of the house/heat pump system, the study found that

Ergodic Convergence Times For Molecular Liquids

January 22, 2010
Author(s)
Raymond D. Mountain
A problem common to all molecular dynamics and Monte Carlo simulations used to estimate fluid properties is how to decide when adequate sampling of the phase space of the system has been realized. One procedure for addressing the sampling question is to

View subspaces for indexing and retrieval of 3D models

January 21, 2010
Author(s)
Helin Dutagaci, Afzal A. Godil, Bulent Sankur, Yucel Yemez
View-based indexing schemes for 3D object retrieval is gaining popularity since they provide good retrieval results. These schemes are coherent with the theory that humans recognize objects based on their 2D appearances. The view-based techniques also

Fabrication of GaAs/AlOx micropillars for small mode volume

January 20, 2010
Author(s)
Richard P. Mirin
Micropillar devices have shown promise as single photon sources for applications in quantum key distribution as well as single photon metrology and fundamental science. For higher temperature operation (77K), a high quality (Q) factor cavity and a small

Metabolomic Analysis of Atlantic Blue Crab, Callinectes sapidus, Hemolymph Following Oxidative Stress

January 20, 2010
Author(s)
Tracey Johnston, Dan Bearden, Arezue Boroujerdi, David A. Stancyk, Lindy Thibodeaux, Karen G. Burnett, Louis E. Burnett
The Atlantic blue crab, Callinectes sapidus, is an economically, ecologically and recreationally valuable decapod crustacean that inhabits estuaries along the Atlantic and Gulf coasts of the United States. In their natural environment, blue crabs are

Phase Diagram of Magnetic Nanodisks measured by SEMPA

January 20, 2010
Author(s)
Seok-Hwan Chung, Robert D. McMichael, Daniel T. Pierce, John Unguris
We use Scanning Electron Microscopy with Polarization Analysis (SEMPA) to image the magnetic domain structures of individual ferromagnetic nanodisks with different diameters and thicknesses, and thereby determine the phase diagram of the magnetic ground

The Semantics of Modules in Common Logic

January 20, 2010
Author(s)
Fabian M. Neuhaus
Common Logic (CL) is an ISO standard that specifies a family of knowledge representation languages. The function of modules within CL is to support local context with a local domains of discourse. Modules play a crucial role since they enable users to

Solvent Retention In Thin Spin-Coated Polystyrene And Poly(Methyl Methacrylate) Homopolymer Films Studied By Neutron Reflectometry

January 19, 2010
Author(s)
Xiaohua Zhang, Kevin G. Yager, Shuhui Kang, Nathaniel J. Fredin, Bulent Akgun, Sushil K. Satija, Jack F. Douglas, Alamgir Karim, Ronald L. Jones
We utilize neutron reflectometry (NR) to probe the amount of residual solvent inside thin polystyrene (PS) and poly(methyl methacrylate) (PMMA) films spin-coated from deuterated toluene polymer solutions onto silicon substrates . The effect of thermal
