Here are some recent papers in ps or pdf format.
The pdf files from journals look good.  The pdf files I created with
ps2pdf are so-so.

bayes_freq--preprint of tutorial with Luis Tenorio on Bayesian and 
frequentist methods of inference, and the role of prior information.

bayes_vs_occam--paper with Wences Gouveia on resolution in waveform inversion
from two different standpoints.  Explains why regularization is different 
than using a priori information. 

domaindecomp--paper with Alberto Villarreal on how to do explicit finite
difference in parallel on a network of workstations.

imaging_inversion--draft of a paper comparing migration and waveform inversion.

local_bayes--preprint of paper with Fernando Moraes to appear in GJI showing
a new approximation for incorporating local information into Bayesian 
inversion.

lyapunov--paper with Erik Van Vleck showing numerical schemes for computing
Lyapunov exponents for wave propagation in random media and how these are
related to the localization length.

montecarlo--paper with Erik Van Vleck and Chris Morey showing new scheme for
adaptively selecting parameters for Monte Carlo optimization.

multiple_scattering--paper with Kasper Van Wijk on laboratory results for
surface wave multiple scattering in a disordered medium.

nature_wave--paper with Roel Snieder on "What is a wave?"

noise_disc--preprint of a tutorial with Luis Tenorio and Roel Snieder on 
various aspects of noise and discretization in inverse problems.

tri_chaos--paper with Roel Snieder discussing particle versus wave chaos and
the stability of time-reversed imaging under perturbations of various types.
