Structural constraints on the evolution of the collagen fibril: convergence on a 1014-residue COL domain [PDF]
Open Biology, 2015 Type I collagen is the fundamental component of the extracellular matrix. Its α1 gene is the direct descendant of ancestral fibrillar collagen and contains 57 exons encoding the rod-like triple-helical COL domain. We trace the evolution of the COL domain

Metastability in the evolution of triple systems [PDF]
Monthly Notices of the Royal Astronomical Society, 2003 The dynamical evolution of 15 000 equal-mass triple systems with zero initial velocities (the free-fall three-body problem) is considered. The equations of motion are numerically integrated using regularization of binary and triple encounters. We find 170 triple systems which reach a state where the motions take place within a limited region of phase ...

Evolution of the Louisiade triple junction [PDF]
Journal of Geophysical Research: Solid Earth, 1999 We derived new finite rotations for the opening of the Coral Sea using revised magnetic anomaly interpretations and fracture zone data from a gravity anomaly grid based on from satellite altimetry. These rotations differ from the finite rotations that describe the opening of the Tasman Sea; this confirms the existence of a triple junction between the ...

The Triple Helix of University-Industry-Government Relations [PDF]
, 2012 Etzkowitz & Leydesdorff (2000) further elaborated the Triple Helix of University-Industry-Government Relations (cf. Etzkowitz & Leydesdorff, 1995; Lowe, 1982) into a model for studying knowledge-based economies.

Ultrasonic velocity variation of Ti6Al4V Ti-alloy bars under conventional forging combined with triple heat treatment [PDF]
MATEC Web of Conferences, 2020 In this paper, the microstructure evolution and ultrasonic velocity variation of Ti6Al4V Ti-alloy bars under different conventional forging deformation degrees and triple heat treatment were investigated, it was found that the the orientation of ...

Can processes make relationships work? The Triple Helix between structure and action [PDF]
, 2014 This contribution seeks to explore how complex adaptive theory can be applied at the conceptual level to unpack Triple Helix models. We use two cases to examine this issue – the Finnish Strategic Centres for Science, Technology & Innovation (SHOKs) and ...

Point process microstructural model of metallic thin films with implications for coarsening
npj Computational Materials, 2023 We develop a thin-film microstructural model that represents structural markers (i.e., triple junctions in the two-dimensional projections of the structure of films with columnar grains) in terms of a stochastic, marked point process and the ...

Sensitivity analysis for optimal control problems governed by nonlinear evolution inclusions
Advances in Nonlinear Analysis, 2017 We consider a nonlinear optimal control problem governed by a nonlinear evolution inclusion and depending on a parameter λ. First we examine the dynamics of the problem and establish the nonemptiness of the solution set and produce continuous selections ...

Fossile to bio : The carbon footprint of distribution of fuel
, 2023 Trots att ökad användning av biodrivmedel anses vara viktig för att uppnå klimatmålen i Sverige och EU, råder det idag brist på kunskap om hur produktionen och distributionen av biodrivmedel påverkar de svenska växthusgasutsläppen.
