Reconstruction of a conformally Euclidean metric from local boundary diffraction travel times
Maarten V. de Hoop, Sean F. Holman, Einar Iversen +2
We consider a region in with boundary and a metric on conformal to the Euclidean metric. We analyze the inverse problem, originally formulat…
Parsimonious module inference in large networks
Tiago P. Peixoto
We investigate the detectability of modules in large networks when the number of modules is not known in advance. We employ the minimum description length (MDL) principle which see…
Quantitative Current-Voltage Characteristics in Molecular Junctions from First Principles
Pierre Darancet, Jonathan R. Widawsky, Hyoung Joon Choi +2
Using self-energy-corrected density functional theory (DFT) and a coherent scattering-state approach, we explain current-voltage (IV) measurements of four pyridine-Au and amine-Au…
Topological equivalence for discontinuous random dynamical systems and applications
Huijie Qiao, Jinqiao Duan
After defining non-Gaussian Lévy processes for two-sided time, stochastic differential equations with such Lévy processes are considered. Solution paths for these stochastic differ…
Attractors for processes on time-dependent spaces. Applications to wave equations
Monica Conti, Vittorino Pata, Roger Temam
For a process U(t,s) acting on a one-parameter family of normed spaces, we present a notion of time-dependent attractor based only on the minimality with respect to the pullback at…
Modeling the Influence of Antifreeze Proteins on Three-Dimensional Ice Crystal Melt Shapes using a Geometric Approach
Jun Jie Liu, Yangzong Qin, Maya Bar Dolev +3
The melting of pure axisymmetric ice crystals has been described previously by us within the framework of so-called geometric crystal growth. Nonequilibrium ice crystal shapes evol…
