Tight-Binding Theory of Quantum Dot Arrays: InAs Dots

October 12, 2021
Author(s)
Javier Aizpurua, G C. Bryant, W Jaskolski
We model the electronic structure and optical properties of coupled self-assembled dots and period dot arrays by use of tight-binding theory. Coupling in dot molecules and dot arrays modifies significantly the level ordering and state symmetries. We show

Time-Domain Processing to Determine Free Space Antenna Factor

October 12, 2021
Author(s)
Dennis G. Camell, Robert Johnk
This paper demonstrates the usefulness of time-domain processing to determine free-space antenna factors (FSAF) for EMC antennas. Procedures are explained and data is provided from 30 MHz to 9 GHz. We investigate time gating of dense frequency packed

Tin Whisker Test Method Development

October 12, 2021
Author(s)
Valeska Schroeder, P Bush, Nick Vo, Maureen E. Williams
In response to legislation banning Pb from electronics, any component suppliers plan to implement tin-based lead-free surfaces finishes to replace current Sn-Pb finishes. The industry needed a test for assessing the susceptibilty of tin-based finishes to

Titanic, The Anatomy of a Disaster -- A Report From the Marine Forensic Panel [SD-7]

October 12, 2021
Author(s)
W H. Garzke, D K. Brown, P K. Matthias, R Cullimore, D Wood, D Livingstone, H P. Leighly, Timothy J. Foecke, A Sandiford
W98-0170 Withdrawn by Author on 02/02/98: Please withdraw WERB Manuscript W98-0170 from consideration. It was entitled 'Titanic: Anatomy of a Disaster . . .' I am removing myself as coauthor to satisfy the concerns of WERB with the least commitment of time

Towards Clinical Application of Methylated DNA Sequences as Cancer Biomarkers: A Joint NCI s EDRN & NIST Workshop on Standards, Methods, Assays, Reagents and Tools (SMART)

October 12, 2021
Author(s)
J Kagan, S Srivastava, Peter E. Barker, S Belinsky, P Cairns
Numerous studies have demonstrated the promise of DNA methylation of cancer genes as potential biomarkers for clinical application in the risk, diagnosis and prognosis of cancer. Barriers to more rapid validation and application include the selection of

Towards Metrological Traceability for DNA Fragment Ratios in GM Quantitation. Part A The Effect of DNA Extraction Methods on the Quantitative Determination of Bt176 Corn by Real-Time PCR

October 12, 2021
Author(s)
Ph Corbisier, W Boothaerts, S Giorio, Heinz Schimmel, M J. Burns, A Baoutina, K R. Emslie, S Furui, Y Kurosawa, Marcia J. Holden, H H. Kim, Y M. Lee, M Kawaharasake, D. W. Sin, J. Wang
An international CCQM-P60 pilot study involving 8 national metrological institutes was organized to investigate if the quantification of genetically modified (GM) corn powder by real-time PCR was affected by the DNA extraction methods applied. Four

Towards Optimization of Patterned Superhydrophobic Surfaces

October 12, 2021
Author(s)
Bharat Bhushan, Michael Nosonovsky, Yong C. Jung
Experimental and theoretical study of wetting properties of patterned Si surfaces with cylindrical flat-top pillars of various sizes and pitch distances is presented. The values of the contact angle (CA), contact angle hysteresis (CAH) and tilt angle (TA)

Toxic Potency Values for Smoke from Products and Materials

October 12, 2021
Author(s)
J L. Neviaser, Richard Gann
Many devices have been used to generate data on the toxic potency of smoke from burning products and materials. This paper critically reviews those apparatus and sorts them by the combustion conditions (related to a type of fire) producing the smoke, the

Transient Phenoxyl Radicals: Formation and Properties in Aqueous Solutions

October 12, 2021
Author(s)
S Steenken, Pedatsur Neta
This chapter discusses the various methods of formation of phenoxyl radicals (oxidation of phenols by metal ions, by free radicals and radical cations, reaction of phenols with hydroxyl radicals, autoxidation of phenols, etc.) and the properties of
