A review of fatigue crack growth for pipeline steels exposed to hydrogen

November 30, 2010
Author(s)
Nicholas Nanninga, Andrew J. Slifka, Yaakov Levy, Calvin L. White
Hydrogen pipeline systems offer an economical means of storing and transporting energy in the form of hydrogen gas. Pipelines can be used to transport hydrogen that has been generated at solar and wind farms to and from salt cavern storage locations. In

Broadband Measurements of Nanofiber Devices: Repeatability and Random Error Analysis

November 30, 2010
Author(s)
Thomas M. Wallis, Atif A. Imtiaz, SangHyun S. Lim, Pavel Kabos, Kichul Kim, Paul Rice, Dejan Filipovic
On-wafer, broadband measurements of two-port nanofiber devices were made in order to test the short-term repeatability of a widely used measurement approach that builds on established on-wafer calibration techniques. The test devices used in this study

Cryptanalysis of the ESSENCE Family of Hash Functions

November 30, 2010
Author(s)
Nicky Mouha , Gautham Sekar, Jean-Philippe Aumasson , Thomas Peyrin, Soren S. Thomsen , Meltem Sonmez Turan, Bart Preneel
ESSENCE is a family of cryptographic hash functions, accepted to the first round of NIST's SHA-3 competition. This paper presents the first known attacks on ESSENCE. We present a semi-free-start collision attack on 31 out of 32 rounds of ESSENCE-512

Electrospray Tandem Quadrupole Fragmentation of Quinolone Drugs and Related Ions. On the Reversibility of Water Loss from Protonated Molecules

November 30, 2010
Author(s)
Pedatsur Neta, Bhaskar Godugu, Yuxue Liang, Yamil Simon, Xiaoyu Yang, Stephen E. Stein
Selected reaction monitoring (SRM) of quinolone drugs showed1 different sensitivities in aqueous solution vs. biological extract. The authors suggested formation of two singly protonated ions with different behavior, one undergoing loss of H 2O and the

Predicting Segmentation Accuracy for Biological Cell Images

November 29, 2010
Author(s)
Adele P. Peskin, Alden A. Dima, Joe Chalfoun
We have performed image segmentations on a very large number of images, using a wide variety of imaging conditions and cell lines, in order to study trends in the segmentation results and make predictions about segmentation accuracy. Comparing results from

Time-division SQUID multiplexers with reduced sensitivity to external magnetic fields

November 29, 2010
Author(s)
Greg Stiehl, Hsiao-Mei Cho, Gene C. Hilton, Kent D. Irwin, John A. Mates, Carl D. Reintsema, Barry L. Zink
We have developed time-division SQUID multiplexers to read out large arrays of transition-edge sensor (TES) detectors. These multiplexers are used in many applications that require exquisite control of systematic error. One important application is the
