Sequence‐Encoded Frustration Directs the Formation of Abridged G‐Quadruplex Architectures

Angewandte Chemie, EarlyView.
Programmable frustration reshapes the free‐energy surface (FES) of guanine‐quadruplex (G4) folding, stabilizing an abridged G4 and a G‐triplex intermediate. ABSTRACT Frustration—competing interactions that cannot be simultaneously optimized—shapes energy landscapes in proteins and soft matter, but has rarely been exploited as a programmable design ...

First-principles statistical mechanics study of the stability of a sub-nanometer thin surface oxide in reactive environments: CO oxidation at Pd(100) [PDF]

, 2006
We employ a multiscale modeling approach to study the surface structure and composition of a Pd(100) model catalyst in reactive environments. Under gas phase conditions representative of technological CO oxidation (~1 atm, 300-600 K) we find the system ...

Use of high-intensity data to define large river management units: A case study on the lower Waikato River, New Zealand [PDF]

, 2014
The importance of environmental heterogeneity in lotic ecosystems is well recognised in river management, and continues to underpin studies of hierarchical patch dynamics, geomorphology and landscape ecology. We evaluated how physical characteristics and

Pseudoscalar Mass Effects in Decays of Taus with Three Pseudoscalar Mesons

, 1993
We study the effects of non-vanishing pseudoscalar masses in $\tau$ decays into three mesons. The hadronic matrix elements are obtained by using the generalized structure of the chiral currents with nonvanishing pseudoscalar masses and implementing the ...
