Fast optimization algorithms and the cosmological constant

November 1, 2017
Author(s)
Stephen P. Jordan, Ning Bao, Brad Lackey, Raphael Bousso
Denef and Douglas have observed that in certain landscape models the problem of finding small values of the cosmological constant is a large instance of an NP-hard problem. The number of elementary operations (quantum gates) needed to solve this problem by

Localized fire tests on steel beams with different end restraints

November 1, 2017
Author(s)
Selvarajah Ramesh, Mina S. Seif, Lisa Choe
Two 6.2-m span I-shaped structural steel beams were tested under combined structural and open flame localized fire loads. Two different support conditions for the beam ends were considered: (i) simple support, and (ii) double-angles bolted to laterally

Microwave Evaluation of Electromigration Susceptibility in Advanced Interconnects

November 1, 2017
Author(s)
Yaw S. Obeng, Kin P. Cheung, Dmitry Veksler, Christopher E. Sunday
Traditional metrology has been unable to adequately address the needs of emerging integrated circuits (ICs) at the nano scale; thus, new metrology and techniques are needed. For example, the reliability challenges in fabrication need to be well understood

Radiative rates of transitions from the 2s2p3 5Sdeg2 state in neutral carbon

November 1, 2017
Author(s)
Alexander Kramida, Haris Kunari
The measured radiative rates of the 2s22p2 3P1,2 – 2s2p3 5S°2 intercombination transitions in neutral carbon reported in the literature are critically evaluated in comparison with theoretical results. The experimental and theoretical values are compared

STRSeq: A catalog of sequence diversity at human identification Short Tandem Repeat loci

November 1, 2017
Author(s)
Katherine Gettings, Lisa Borsuk, D Ballard, Martin Bodner, Bruce Budowle, Laurence Devesse, Jonathan King, W. Parson, Christopher Phillips, Peter Vallone
The STR Sequencing Project (STRSeq) was initiated to facilitate the description of sequence- based alleles at the Short Tandem Repeat (STR) loci targeted in human identification assays. This international collaborative effort, which has been endorsed by

The effect of self-consistent potentials on EXAFS analysis

November 1, 2017
Author(s)
Bruce Ravel, M. Newville, Josh J. Kas, John J. Rehr
We present an EXAFS-oriented theory program based on the popular Feff8 and providing an application programming interface designed to make it easy to integrate high-quality theory into EXAFS analysis software. We then use this new code to examine the

The Iterated Random Function Problem

November 1, 2017
Author(s)
Ritam Bhaumik, Nilanjan Datta, Avijit Dutta, Nicky Mouha, Mrudil Nandi
At CRYPTO 2015, Minaud and Seurin introduced and studied the iterated random permutation problem, which is to distinguish the r-th iterate of a random permutation from a random permutation. In this paper, we study the closely related iterated random

The Momentum Distribution of Liquid 4 He

November 1, 2017
Author(s)
Timothy R Prisk, M. S. Bryan, P. E. Sokol, G. E. Granroth, S. Moroni, M. Boninsegni
We report high-resolution neutron Compton scattering measurements of liquid 4He under saturated vapor pressure. There is excellent agreement between the observed scattering and ab initio predictions of its lineshape. quantum Monte Carlo calculations

The role of human monoacylglycerol lipase (hMAGL) binding pocket in breakup of unsaturated phospholipid membranes

November 1, 2017
Author(s)
Ioannis L. Karageorgos, Vitalii I. Silin, nikolai zvonok, John P. Marino, David Janero, Alexandros Makriyannis
Human monoacylglycerol lipase (hMAGL) plays a key role in homeostatic tuning of the endocannabinoid signaling system and supports aggressive tumorogenesis, making this enzyme a promising therapeutic target. hMAGL features a membrane-associated lid domain

Using realistic factors to simulate catastrophic congestion events in a network

November 1, 2017
Author(s)
Kevin L. Mills, Christopher E. Dabrowski
With the rapid growth of the Internet, there has been increased interest in the use of computer models to study the dynamics of communication networks in the research literature. An important example of this has been the study of dramatic, but relatively

Improving Software Assurance through Static Analysis Tool Expositions

October 31, 2017
Author(s)
Terry S. Cohen, Damien J. Cupif, Aurelien M. Delaitre, Charles Daniel De Oliveira, Elizabeth N. Fong, Vadim Okun
Multiple techniques and tools prove effective for software assurance. One technique that has grown in acceptance since the early 2000s is static analysis, which examines software for weaknesses without executing it. The National Institute of Standards and
