Impact‐Induced Porosity and Microfracturing at the Chicxulub Impact Structure
Journal of Geophysical Research: Planets, 2019 Porosity and its distribution in impact craters has an important effect on the petrophysical properties of impactites: seismic wave speeds and reflectivity, rock permeability, strength, and density.

Price Impact on Term Structure [PDF]
SSRN Electronic Journal, 2020 We introduce a first theory of price impact in presence of an interest-rates term structure. We explain how one can formulate instantaneous and transient price impact on bonds with different maturities, including a cross price impact that is endogenous to the term structure.

The structural impact of DNA mismatches [PDF]
Nucleic Acids Research, 2015 The structure and dynamics of all the transversion and transition mismatches in three different DNA environments have been characterized by molecular dynamics simulations and NMR spectroscopy. We found that the presence of mismatches produced significant local structural alterations, especially in the case of purine transversions.

Riesite, a New High Pressure Polymorph of TiO2 from the Ries Impact Structure
Minerals, 2020 This paper describes riesite, a new high-pressure polymorph of TiO2 from the Ries impact structure, Germany. Riesite occurs in shock-induced melt veins within xenoliths of bedrock in suevite. It is structurally closely related to srilankite from which it
