Probing microplasticity in small scale FCC crystals via Dynamic Mechanical Analysis
Xiaoyue Ni, Stefanos Papanikolaou, Gabriele Vajente +2
In small-scale metallic systems, collective dislocation activity has been correlated with size effects in strength and with a step-like plastic response under uniaxial compression…
Star formation towards the Galactic HII region RCW120
M. Figueira, A. Zavagno, L. Deharveng +16
The expansion of HII regions can trigger the formation of stars. An overdensity of young stellar objects (YSOs) is observed at the edges of HII regions but the mechanisms that give…
Nonparametric estimation of conditional value-at-risk and expected shortfall based on extreme value theory
Carlos Martins-Filho, Feng Yao, Maximo Torero
We propose nonparametric estimators for conditional value-at-risk (CVaR) and conditional expected shortfall (CES) associated with conditional distributions of a series of returns o…
Polychromatic colorings of complete graphs with respect to 1-,2-factors and Hamiltonian cycles
Maria Axenovich, John Goldwasser, Ryan Hansen +5
If G is a graph and H is a set of subgraphs of G, then an edge-coloring of G is called H-polychromatic if every graph from H gets all colors present in G on its edges. The H-polych…
The NANOGrav Nine-Year Data Set: Measurement and Interpretation of Variations in Dispersion Measures
M. L. Jones, M. A. McLaughlin, M. T. Lam +21
We analyze dispersion measure (DM) variations of 37 millisecond pulsars in the 9-year NANOGrav data release and constrain the sources of these variations. Variations are significan…
The NANOGrav Nine-Year Data Set: Excess Noise in Millisecond Pulsar Arrival Times
M. T. Lam, J. M. Cordes, S. Chatterjee +22
Gravitational wave astronomy using a pulsar timing array requires high-quality millisecond pulsars, correctable interstellar propagation delays, and high-precision measurements of…
