Intrinsic energy localization through discrete gap breathers in one-dimensional diatomic granular crystals by Theocharis, G., Boechler, Nicholas, Kevrekidis, P. G., Job, S., Porter, Mason A., Daraio, Chiara

“…We investigate their existence, structure, and stability throughout the band gap of the linear spectrum and classify them into four regimes: a regime near the lower optical band edge of the linear spectrum, a moderately discrete regime, a strongly discrete regime that lies deep within the band gap of the linearized version of the system, and a regime near the upper acoustic band edge. …”

Maximizing Reliability in WDM Networks through Lightpath Routing by Lee, Hyang Won, Lee, Kayi, Modiano, Eytan H

“…We show that in general the optimal lightpath routing depends on the link failure probability, and characterize the properties of lightpath routings that maximize the reliability in different failure probability regimes. In particular, we show that in the low failure probability regime, maximizing the “cross-layer” min cut of the (layered) network maximizes reliability, whereas in the high failure probability regime, minimizing the spanning tree of the network maximizes reliability. …”

Comparison of computational algorithms for simulating an electrospray plume with a n-body approach by Hampl, Sebastian K., Waggoner, Marshall T., Gallud Cidoncha, Ximo, Petro, Elaine M., Lozano, Paulo C.

“…Abstract In order to better evaluate the trade-offs between different simulation options for an electrospray thruster plume, we have developed a multi-scale n-body code to compute the evolution of a single emitter electrospray plume in the pure ionic regime. The electrostatic force computations in the simulation are captured through the use of three different computational algorithms with various degrees of approximation. …”

Additively Manufactured Polyetheretherketone (PEEK) with Carbon Nanostructure Reinforcement for Biomedical Structural Applications by Alam, Fahad, Varadarajan, Kartik M, Koo, Joseph H, Wardle, Brian L, Kumar, Shanmugam

“…CNS/PEEK scaffolds and bulk specimens, realized via fused filament fabrication (FFF) additive manufacturing, are assessed primarily in the low-strain linear-elastic regime. 3D printed PEEK nanocomposites are found to have enhanced mechanical properties in all cases while maintaining the desired degree of crystallinity in the range of 30–33%. …”

Terahertz and infrared nonlocality and field saturation in extreme-scale nanoslits by Vidal-Codina, Ferran, Martín-Moreno, Luis, Ciracì, Cristian, Yoo, Daehan, Nguyen, Ngoc-Cuong, Oh, Sang-Hyun, Peraire, Jaime

“…We study the impact of gap width, film thickness and electron motion model on the plasmon resonances of the slit for two different frequency regimes: (1) terahertz frequencies, which lead to 1000-fold field amplitude enhancements that saturate as the gap shrinks; and (2) the near- and mid-infrared regime, where we show that narrow gaps and thick films cluster Fabry-Pérot (FP) resonances towards lower frequencies, derive a dispersion relation for the first FP resonance, in addition to observing that nonlocality boosts transmittance and reduces enhancement.…”

Inferring electrospray emission characteristics from molecular dynamics and simulated retarding potential analysis by Schroeder, Madeleine, Gallud, Ximo, Petro, Elaine, Jia-Richards, Oliver, Lozano, Paulo C

“…In this work, we present coordinated molecular dynamics, ion cluster acceleration, and retarding potential analysis simulations to determine cluster fragmentation behavior in a realistic emitter geometry for electrosprays operating in the pure ionic regime. Molecular dynamics simulations are used to determine the fragmentation rates of ionic liquid clusters as a function of internal energy, electric field strength, and cluster size. …”

Examining flow-flame interaction and the characteristic stretch rate in vortex-driven combustion dynamics using PIV and numerical simulation by Speth, Raymond L., Ghoniem, Ahmed F., Hong, Seung hyuck, Shanbhogue, Santosh

“…Pressure measurements and high speed particle image velocimetry (PIV) are used to generate pressure response curves and phase-averaged vorticity and streamlines as well as the instantaneous flame front, respectively, which describe unsteady flame and flow dynamics in each operating regime. This work was motivated in part by our earlier study where we showed that the strained flame consumption speed S[subscript c] can be used to collapse the pressure response curves over a wide range of operating conditions. …”

CELLO: A fast algorithm for Covariance Estimation by Vega-Brown, William R, Bachrach, Abraham Galton, Bry, Adam P., Roy, Nicholas, Kelly, Jonathan S.

“…We show that in experiments, CELLO learns to predict measurement covariances that agree with empirical covariances obtained by manually annotating sensor regimes. We also show that using the learned covariances during filtering provides substantial quantitative improvement to the overall state estimate. © 2013 IEEE.…”
