Deterministic numerical solutions of the Boltzmann equation using the fast spectral method [PDF]
, 2013 The Boltzmann equation describes the dynamics of rarefied gas flows, but the multidimensional nature of its collision operator poses a real challenge for its numerical solution. In this paper, the fast spectral method [36], originally developed by Mouhot

DNS and LES for Simulating Stratocumulus: Better Together
Journal of Advances in Modeling Earth Systems, 2018 We argue that combining direct numerical simulation (DNS) with large‐eddy simulation (LES) and field studies could accelerate current lines of stratocumulus research.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Direct numerical simulations of forced and unforced separation bubbles on an airfoil at incidence [PDF]
, 2008 Direct numerical simulations (DNS) of laminar separation bubbles on a NACA-0012 airfoil at Re-c = 5 x 10(4) and incidence 5 degrees are presented. Initially volume forcing is introduced in order to promote transition to turbulence.

Direct numerical simulations of aeolian sand ripples [PDF]
Proceedings of the National Academy of Sciences, 2014 Significance Wind ripples decorate the flanks of dunes in amazingly regular patterns, on both Earth and Mars. Their emergence at a wavelength much larger than the grain size is currently unexplained. We report direct numerical simulations of grains interacting with a wind flow that are, for the first time to our knowledge, able to reproduce ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations
FEBS Letters, EarlyView.The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...
