Bendix: intuitive helix geometry analysis and abstraction

A. C. E. Dahl, M. Chavent, M. S. P. Sansom
2012 Bioinformatics  
Software is presented that quantifies and projects the helix axis evolution over time, with the choice of uniform or analytic heatmap graphics according to the local geometry.  ...  The flexibility of α-helices is important for membrane protein function and calls for better visualization and analysis.  ...  We thank Oliver Beckstein, Philip Fowler, Sarah Rouse and Ben Hall for suggesting features and testing the software.  ...

Uncertainty-aware visualization techniques [article]

Christoph Schulz, Universität Stuttgart
2022
Whether and how we present this uncertainty can have a major impact on how our audience perceives such information. Still, uncertainty is rarely visualized and communicated.  ...  The focus lies on modeling, propagation, and visualization of uncertainty. As encodings of uncertainty, we propose wave-like splines and sampling-based transparency.  ...  For example, VMD offers the option to depict helices as thick, straight cylinders encompassing the whole helix or as thick tubes that follow the centerline of the helix (Bendix representation [DCS12]  ...

Protein crowding mediates membrane remodeling in upstream ESCRT-induced formation of intraluminal vesicles

Susanne Liese, Eva Maria Wenzel, Ingrid Kjos, Rossana Rojas Molina, Sebastian W. Schultz, Andreas Brech, Harald Stenmark, Camilla Raiborg, Andreas Carlson
2020 Proceedings of the National Academy of Sciences of the United States of America  
Combining experimental measurements and electron microscopy analysis of ESCRT-III–depleted cells with a mathematical model, we show that upstream ESCRT-induced alteration of the Gaussian bending rigidity  ...  and their crowding in concert with the transmembrane cargo on the membrane induce membrane deformation and facilitate ILV formation: Upstream ESCRT-driven budding does not require ATP consumption as only  ...  Non-dimensional analysis A usual step of analysis consists in finding the dimensionless form of both the shape equations and the boundary conditions.  ...
