Quasicontinuum Models of Interfacial Structure and Deformation
V. B. Shenoy, R. Miller, E. B. Tadmor +2
Microscopic models of the interaction between grain boundaries (GBs) and both dislocations and cracks are of importance in understanding the role of microstructure in altering the…
Tracing Cryptocurrency Scams: Clustering Replicated Advance-Fee and Phishing Websites
R. Phillips, H. Wilder
Over the past few years, there has been a growth in activity, public knowledge, and awareness of cryptocurrencies and related blockchain technology. As the industry has grown, ther…
VLBI observations at 147 GHz: first detection of transatlantic fringes in bright AGN
T. P. Krichbaum, D. A. Graham, W. Alef +21
At 147 GHz (2mm wavelength), we detected three prominent AGN (NRAO150, 3C279, 1633+382) with Very Long Baseline Interferometry (VLBI) with an angular resolution of only 18 micro-ar…
Structure and Strength of Dislocation Junctions: An Atomic Level Analysis
D. Rodney, R. Phillips
The quasicontinuum method is used to simulate three-dimensional Lomer-Cottrell junctions both in the absence and in the presence of an applied stress. The simulations show that thi…
Calibration of Tethered Particle Motion Experiments
L. Han, B. Lui, S. Blumberg +3
The Tethered Particle Motion (TPM) method has been used to observe and characterize a variety of protein-DNA interactions including DNA looping and transcription. TPM experiments e…
Mesoscopic Analysis of Structure and Strength of Dislocation Junctions in FCC Metals
V. B. Shenoy, R. V. Kukta, R. Phillips
We develop a finite element based dislocation dynamics model to simulate the structure and strength of dislocation junctions in FCC crystals. The model is based on anisotropic elas…
2mm Wavelength VLBI of SiO Masers and AGN
S. Doeleman, R. Phillips, A. Rogers +21
In April 2002 an array of antennas operating at 129GHz successfully detected VLBI fringes on both continuum AGN and SiO maser sources. The 129GHz fringes on maser sources represent…
An Adaptive Finite Element Approach to Atomic-Scale Mechanics - The Quasicontinuum Method
V. B. Shenoy, R. Miller, E. B. Tadmor +3
Mixed atomistic and continuum methods offer the possibility of carrying out simulations of material properties at both larger length scales and longer times than direct atomistic c…
