A Layered Graphical Model for Cloud Forensic and Mission Impact Analysis

February 1, 2019
Author(s)
Changwei Liu, Anoop Singhal, Duminda Wijesekera
In this paper, we describe a layered graphical model to analyze the impact of cyber attacks on business processes and services. Our model has three layers: the upper layer models the business processes and their dependencies. The middle layer constructs

A status of temporal trends of persistent organic pollutants in Arctic biota

February 1, 2019
Author(s)
Frank Riget, Anders Bignert, Birgit Braune, Maria Dam, Rune Dietz, Marlene Evans, Norman Green, Helga Gunnlaugsdottir, Katrin S. Hoydal, John Kucklick, Robert Letcher, Derek Muir, Stacy Schuur, Christian Sonne, Stern Gary, Gregg Tomy, Katrin Vorkamp, Simon Wilson
More than 1000 time-series of persistent organic pollutants (POPs) in Arctic biota from marine and freshwater ecosystems some extending back to the beginning of 1980s were analyzed using a robust statistical method. The Arctic area encompassed extended

Coherent light brightens the frontier of quantum science and technology

February 1, 2019
Author(s)
Jun Ye, Margaret Murnane
The precise control of coherent light across a vast spectral span has enabled revolutionary progress in precision measurements and the quantum control of atomic, molecular, and condensed matter systems. The laser was invented about 60 years ago (1) — 30

Elliptic Curves Arising from Triangular Numbers

February 1, 2019
Author(s)
Abhishek Juyal, Shiv D. Kumar, Dustin Moody
We study the Legendre family of elliptic curves E_t : y^2 = x(x − 1)(x − ∆t), parametrized by triangular numbers ∆t = t(t + 1)/2. We prove that the rank of E_t over the function field Q(t) is 1, while the rank is 0 over Q(t). We also produce some infinite

Optimization of Reflectometry Experiments using Information Theory

February 1, 2019
Author(s)
Bradley W. Treece, Paul A. Kienzle, David Hoogerheide, Charles Majkrzak, Mathias Loesche, Frank Heinrich
A method based on Bayesian statistics and information theory is developed to analyze the information gain Δ}H of surface-sensitive reflectometry experiments. After presenting the underlying mathematical framework and its implementation, the method is

Propagating Measurement Uncertainty to Microwave Amplifier Nonlinear Behavioral Models

February 1, 2019
Author(s)
Dylan F. Williams, Laurence T. Stant, Martin J. Salter, Nick M. Ridler, Peter Aaen
We propagate for the first time correlated measurement uncertainties into a nonlinear behavioral model of a millimetre-wave amplifier. We make use of the NIST Microwave Uncertainty Framework to evaluate the uncertainties in large-signal electromagnetic

Structural and Dynamical Order of a Disordered Protein: Molecular Insights into Conformational Switching of PAGE4 at the Systems Level

February 1, 2019
Author(s)
Xingcheng Ling, Prakash Kulkarni, Federico Bocci, Nicholas Schafer, Susmita Roy, Min-Yeh Tsai, Yanan He, Yihong Chen, Krithika Rajagopalan, Steven Mooney, Yu Zeng, Keith Weninger, Alexander Grishaev, Jose Onuchic, Herbert Levine, Peter Wolynes, Govindan Rangarajan, Vladimir Uversky, John Orban, Mohit Jolly
Folded proteins show a high degree of structural order and undergo (fairly constrained) collective motions related to their functions. On the other hand, intrinsically disordered proteins (IDPs), while lacking a well-defined three-dimensional structure, do
