Shape Neutral Analysis of Graph-based Data-structures [article]

Gregory J. Duck and Joxan Jaffar and Roland H. C. Yap
2018 arXiv   pre-print
A key property of our program analysis is that the target data-structure properties are shape neutral, i.e., the analysis does not check for properties relating to a given data-structure graph shape, such  ...  Nevertheless, the analysis can detect errors in a wide range of data-structure manipulating programs, including those that use lists, trees, DAGs, graphs, etc.  ...  In particular, the analysis is shape neutral, and does not aim to analyze for, nor enforce, a given shape of the graph.  ...

Shape Neutral Analysis of Graph-based Data-structures

2018 Theory and Practice of Logic Programming  
A key property of our program analysis is that the target data-structure properties are shape neutral, i.e., the analysis does not check for properties relating to a given data-structure graph shape, such  ...  Nevertheless, the analysis can detect errors in a wide range of data-structure manipulating programs, including those that use lists, trees, DAGs, graphs, etc.  ...  None of these properties depend on the shape of the data-structure. Importantly, all of the properties 1-4 are independent of the data-structure shape, i.e. the analysis is shape neutral.  ...

Neutral Networks of Sequence to Shape Maps [article]

Emma Y. Jin, Jing Qin, Christian M. Reidys
2007 arXiv   pre-print
Furthermore, we show that there exists a certain subset of shapes which carries a natural graph structure.  ...  In this graph any two shapes are connected by a path of shapes with respective neutral networks of distance one. We finally discuss our results and provide a comparison with RNA folding maps.  ...  This work was supported by the 973 Project, the PCSIRT Project of the Ministry of Education, the Ministry of Science and Technology, and the National Science Foundation of China.  ...

Gene duplication and subsequent diversification strongly affect phenotypic evolvability and robustness

V. Jouffrey, A. S. Leonard, S. E. Ahnert
2021 Royal Society Open Science  
This model has previously been used in a variety of contexts to model the assembly and evolution of protein quaternary structure.  ...  We study the effects of non-determinism and gene duplication on the structure of genotype–phenotype (GP) maps by introducing a non-deterministic version of the Polyomino self-assembly model.  ...  The first step is to build the allowed necklaces based on the number of interacting and neutral colours.  ...

Form Follows Content: An Empirical Study on Symbol-Content (In)Congruences in Thematic Maps

Silvia Klettner
2020 ISPRS International Journal of Geo-Information  
Symmetric shapes, on the other hand, emerged to be of high congruence with positive and neutral map topics, whilst incongruent with negative topics.  ...  This research, therefore, draws attention to the principle of contextual congruence to study the correspondences between shape symbols and different geospatial content.  ...  Conflicts of Interest: The author declares no conflict of interest.  ...

Sequence-structure relations of pseudoknot RNA

Fenix WD Huang, Linda YM Li, Christian M Reidys
2009 BMC Bioinformatics  
The analysis of sequence-structure relations of RNA is based on a specific notion and folding of RNA structure.  ...  We study properties, like the fraction of pseudoknot structures, the dominant pseudoknot-shapes, neutral walks, neutral neighbors and local connectivity.  ...  These combinatorial properties enable us to assign a unique, loop-based energy. In the course of our analysis we show that an RNA pseudoknot structure can be con-structed via simpler substructures.  ...
