Shape modeling technique KOALA validated by ESA Rosetta at (21) Lutetia
B. Carry, M. Kaasalainen, W. J. Merline +12
We present a comparison of our results from ground-based observations of asteroid (21) Lutetia with imaging data acquired during the flyby of the asteroid by the ESA Rosetta missio…
Large two-dimensional electronic systems: Self-consistent energies and densities at low cost
E. Rasanen, S. Pittalis, G. Bekcioglu +1
We derive a self-consistent local variant of the Thomas-Fermi approximation for (quasi-)two-dimensional (2D) systems by localizing the Hartree term. The scheme results in an explic…
An Algorithm for the Stochastic Simulation of Gene Expression and Heterogeneous Population Dynamics
Daniel A. Charlebois, Jukka Intosalmi, Dawn Fraser +1
We present an algorithm for the stochastic simulation of gene expression and heterogeneous population dynamics. The algorithm combines an exact method to simulate molecular-level f…
Determining the DNA stability parameters for the breathing dynamics of heterogeneous DNA by stochastic optimization
Srijeeta Talukder, Pinaki Chaudhury, Ralf Metzler +1
We suggest that the thermodynamic stability parameters (nearest neighbor stacking and hydrogen bonding free energies) of double-stranded DNA molecules can be inferred reliably from…
Antichain cutsets of strongly connected posets
Stephan Foldes, Russ Woodroofe
Rival and Zaguia showed that the antichain cutsets of a finite Boolean lattice are exactly the level sets. We show that a similar characterization of antichain cutsets holds for an…
BM3D Frames and Variational Image Deblurring
Aram Danielyan, Vladimir Katkovnik, Karen Egiazarian
A family of the Block Matching 3-D (BM3D) algorithms for various imaging problems has been recently proposed within the framework of nonlocal patch-wise image modeling [1], [2]. In…
Spectral decomposition and matrix element effects in scanning tunneling spectroscopy of BiSrCaCuO
Jouko Nieminen, Ilpo Suominen, R. S. Markiewicz +2
We present a Green's function based framework for modeling the scanning tunneling spectrum from the normal as well as the superconducting state of complex materials where the natur…
Effect of orbital symmetry of the tip on Scanning Tunneling Spectra of BiSrCaCuO
Ilpo Suominen, Jouko Nieminen, R. S. Markiewicz +1
We discuss how variations in the scanning tunneling microscope (STM) tip, whether unintentional or intentional, can lead to changes in topographic images and dI/dV spectra. We cons…
Residual mean first-passage time for jump processes: theory and applications to Lévy flights and fractional Brownian motion
Vincent Tejedor, Olivier Bénichou, Ralf Metzler +1
We derive a functional equation for the mean first-passage time (MFPT) of a generic self-similar Markovian continuous process to a target in a one-dimensional domain and obtain its…
The chain sucker: translocation dynamics of a polymer chain into a long narrow channel driven by longitudinal flow
Kaifu Luo, Ralf Metzler
Using analytical techniques and Langevin dynamics simulations, we investigate the dynamics of polymer translocation into a narrow channel of width embedded in two dimensions, d…
First passage behaviour of fractional Brownian motion in two-dimensional wedge domains
J. -H. Jeon, A. V. Chechkin, R. Metzler
We study the survival probability and the corresponding first passage time density of fractional Brownian motion confined to a two-dimensional open wedge domain with absorbing boun…
Effective surface motion on a reactive cylinder of particles that perform intermittent bulk diffusion
Aleksei V. Chechkin, Irwin M. Zaid, Michael A. Lomholt +2
In many biological and small scale technological applications particles may transiently bind to a cylindrical surface. In between two binding events the particles diffuse in the bu…
