Locally optimal unstructured finite element meshes in 3 dimensions [PDF]
, 2004 This paper investigates the adaptive finite element solution of a general class of variational problems in three dimensions using a combination of node movement, edge swapping, face swapping and node insertion.

BS‐RNase tetramers: An example of domain‐swapped oligomers [PDF]
FEBS Letters, 1996 In the ribonuclease superfamily, dimericity is a unique feature of bovine seminal RNase (BS‐RNase). In about two‐thirds of native BS‐RNase molecules, the two subunits interchange their N‐terminal tails, thus generating domain‐swapped dimers (MxM), which mostly responsible for enzyme biological activities and allostericity.

Structural Insights into RNA Dimerization: Motifs, Interfaces and Functions
Molecules, 2020 In comparison with the pervasive use of protein dimers and multimers in all domains of life, functional RNA oligomers have so far rarely been observed in nature.

Multiscale nature of hysteretic phenomena: Application to CoPt-type magnets [PDF]
, 2002 We suggest a workable approach for the description of multiscale magnetization reversal phenomena in nanoscale magnets and apply it to CoPt-type alloys. We show that their hysteretic properties are governed by two effects originating at different length ...

FEBS Letters, EarlyView.Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Swapping of transmembrane domains in the epithelial calcium channel TRPV6
Scientific Reports, 2017 Tetrameric ion channels have either swapped or non-swapped arrangements of the S1–S4 and pore domains. Here we show that mutations in the transmembrane domain of TRPV6 can result in conversion from a domain-swapped to non-swapped fold.

Mobility and asymmetry effects in one-dimensional rock-paper-scissors games
, 2010 As the behavior of a system composed of cyclically competing species is strongly influenced by the presence of fluctuations, it is of interest to study cyclic dominance in low dimensions where these effects are the most prominent.

Domain Swapping in Abiotic Foldamers
Angewandte Chemie International EditionAbstractFoldamer sequences that adopt tertiary helix‐turn‐helix folds mediated by helix‐helix hydrogen bonding in organic solvents have been previously reported. In an attempt to create genuine abiotic quaternary structures, i.e. assemblies of tertiary structures, new sequences were prepared that possess additional hydrogen bond donors at positions ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.
