Structural alterations in breast stromal and epithelial DNA: the influence of 8,5'-cyclo-2'-deoxyadenosine

June 1, 2006
Author(s)
K. M. Anderson, Pawel Jaruga, C. R. Ramsey, N. K. Gilman, V. M. Green, S. W. Rostad, J. T. Emerman, M Miral Dizdar, D. C. Malins
(5'S)-8,5'-Cyclo-2'-deoxyadenosine (S-cdA), which arises from the reaction of the hydroxyl radical (*OH) with 2'-deoxyadenosine in DNA, is a lesion comprising a base-sugar linkage that distorts the DNA backbone. This structure impedes transcription and

The 2006 Upper Ontology Summit Joint Communique

June 1, 2006
Author(s)
Leo Obrst, Patrick Cassidy, Steven R. Ray, Bradford Smith, Dagobert Soergel, Matthew West, Peter Yim
On March 14-15 in Gaithersburg, MD, at the US National Institute of Standards and Technology (NIST), the Upper Ontology Summit (UOS) took place. The Upper Ontology Summit was a convening of custodians of several prominent upper ontologies, key ontology

The National Marine Mammal Tissue Bank Specimen Inventory

June 1, 2006
Author(s)
Rebecca S. Pugh, Michael B. Ellisor, Amanda J. Moors, Paul R. Becker, Barbara J. Porter, Elizabeth A. Mackey, Michele M. Schantz, R. Demiralp, Stephen A. Wise
The National Institute of Standards and Technology (NIST) provides for the cryogenic banking of marine mammal tissues in the National Marine Mammal Tissue Bank (NMMTB). The purpose of the NMMTB is to maintain quality controlled marine mammal tissues to

Thermochemical and Thermophysical Properties of JP-10

June 1, 2006
Author(s)
Thomas J. Bruno, Marcia L. Huber, Arno D. Laesecke, Eric Lemmon, Richard A. Perkins
This report describes measurement and modeling efforts performed on the missile fuel, JP-10. Measurements* include chemical analysis, thermal decomposition kinetics, density, viscosity, speed of sound, thermal conductivity and vapor pressure (distillation

User Interface of Simulation of the Shipbuilding Operations

June 1, 2006
Author(s)
Guodong Shao, Charles R. McLean, Swee K. Leong
This paper discusses the development of the user interface for a simulation of the shipbuilding operations. It presents an overview of a generic simulation of shipbuilding operations, the simulation system's user profiles, and the user interface screen

Wrinkling of Ultrathin Polymer Films

June 1, 2006
Author(s)
Rui Huang, Christopher Stafford, B D. Vogt
This paper presents a bilayer model to account for surface effects on the wrinkling of ultrathin polymer films. Assuming a surface layer of finite thickness, effects of surface properties on the critical strain, the equilibrium wavelength, and the wrinkle

Forensic Tools for Mobile Phone Subscriber Identity Modules

May 31, 2006
Author(s)
Wayne Jansen, Richard Ayers
Cell phones and other handheld devices incorporating cell phone capabilities (e.g., smart phones) are ubiquitous. Besides placing calls, cell phones allow users to perform other tasks such as text messaging and phonebook entry management. When cell phones

Microfabricated atomic clocks and magnetometers

May 31, 2006
Author(s)
Svenja A. Knappe, P Schwindt, Vladislav Gerginov, V Shah, Hugh Robinson, Leo W. Hollberg, John E. Kitching, Li-Anne Liew, John Moreland
We demonstrate the critical subsystems of compact atomic clocks and magnetometers based on microfabricated physics packages. The clock components have a volume below 5 cm 3, a fractional frequency instability below 6x10 -10/τ 1⁄2, and consume 200 mW of

Voltage Versus Magnetic Field Measurements on Nb 3 Sn Wires

May 31, 2006
Author(s)
Loren F. Goodrich
We measured voltage versus magnetic field (V-H}/I}) on commercial Nb 3Sn wires. Typically, voltage-current (V-I) at constant field is measured to determine the critical current (I c). Recently, V-H at constant or ramping current is being measured to assess

Josephson Junction Materials Research Using Phase Qubits

May 30, 2006
Author(s)
Raymond Simmonds, Dustin P. Hite, Robert McDermott, Matthias Steffen, Ken B. Cooper, Kristine Lang, John M. Martinis, David P. Pappas
At present, the performance of superconducting qubits is limited by decoherence. Strong decoherence of phase qubits is associated with spurious microwave resonators residing within the Josephson junction tunnel barrier [1]. In this work, we investigate

Herding Hash Functions and the Nostradamus Attack

May 28, 2006
Author(s)
John M. Kelsey, Tadayoshi Kohno
In this paper, we develop a new attack on Damgaard-Merkle hash functions, called the herding attack, in which an attacker who can find many collisions on the hash function by brute force can first provide the hash of message, and later ''herd'' any given

Selecting Effective Test Sets

May 26, 2006
Author(s)
Leonard E. Gebase, Robert D. Snelick, Roch Bertucat
One of the first problems that must be addressed when attempting to test the reliability of any software implementation is determining what is to be tested. The number of paths an implementation can follow is generally much too large to be able to test all
