Improved Synthesis and Crystal Structure of the Flexible Pillared Layer Porous Coordination Polymer: Ni(1,2-bis(4-pyridyl)ethylene)[Ni(CN)4]

April 4, 2013
Author(s)
Winnie K. Wong-Ng, Jeffrey T. Culp, Yu-Sheng Chen, Peter Zavalij, Laura Espinal, Daniel W. Siderius, Andrew J. Allen, Steve Scheins, Christopher Matranga
A new method of synthesis was developed for the flexible coordination polymer Ni(L)[Ni(CN)4], L=1,2-bis(4-pyridyl)ethylene (bpene) to increase its CO2 sorption uptake. The structure of the newly synthesized bpene has been determined by synchrotron X-ray

Salivary Antigen-5/CAP Family Members Are Cu 2+ -dependent Antioxidant Enzymes That Scavenge O 2 -. and Inhibit Collagen-induced Platelet Aggregation and Neutrophil Oxidative Burst

April 4, 2013
Author(s)
Teresa Assumpcao, Dongying Ma, Alexandra Schwarz, Karine Reiter, Jaime Santana, John Andersen, Jose Ribeiro, Glen Nardone, Lee L. Yu, Ivo Francischetti
The function of the antigen-5/CAP family of proteins found in the salivary gland of bloodsucking animals has remained elusive for decades. Antigen-5 members from the hematophagous insects Dipetalogaster maxima (DMAV) and Triatoma infestans (TIAV) were

Event Identification in He-3 Proportional Counters Using Risetime Discrimination

April 2, 2013
Author(s)
Jeffrey S. Nico, T J. Langford, Christopher D. Bass, E J. Beise, D. K. Erwin, Craig Heimbach
We present a straightforward method for particle identification and background rejection in He-3 proportional counters for use in neutron detection. By measuring the risetime and pulse height of the preamplifier signals, one may define a region in the

A Basic CWE-121 Buffer Overflow Effectiveness Test Suite

April 1, 2013
Author(s)
Paul E. Black, Hsiao-Ming M. Koo, Thomas F. Irish
Phase 3 of MITRE's Common Weakness Enumeration (CWE) Compatibility and Effectiveness program allows a customer to understand how effective a software assurance tool is at finding weaknesses and what code complexities it handles. Phase 3 is based on suites

Distributed Force Probe Bending Model of CD-AFM Bias

April 1, 2013
Author(s)
Vladimir A. Ukraintsev, Ndubuisi George Orji, Theodore V. Vorburger, Ronald G. Dixson, Joseph Fu, Richard M. Silver
Critical Dimension AFM (CD-AFM) is a widely used reference metrology technique. To characterize modern semiconductor devices, small and flexible probes, often 15 nm to 20 nm in diameter, are used. Recent studies have reported uncontrolled and significant

Engineering novel detectors and sensors for MRI

April 1, 2013
Author(s)
Gary Zabow, Chunqi Qian, Alan Koretsky
Increasing detection sensitivity and image contrast have always been major topics of research in MRI. In this perspective, we summarize two engineering approaches to make detectors and sensors that have potential to extend the capability of MRI. The first

Field Standards for Weights and Measures

April 1, 2013
Author(s)
Georgia L. Harris
An article written for the measurement community on whether [field] standards are “fit for purpose”. Is the equipment used is in testing designed for the purpose in which it is being used. The concept of fit for purpose is common in method validation

Logic Minimization Techniques with Applications to Cryptology

April 1, 2013
Author(s)
Joan Boyar, Philip Matthews, Rene Peralta
A new technique for combinational logic optimization is described. The technique is a two-step process. In the rst step, the non-linearity of a circuit as measured by the number of non-linear gates it contains is reduced. The second step reduces the number
