Human Activity as a Manifold-Valued Random Process

IEEE TRANSACTIONS ON IMAGE PROCESSING, 21(8), 3416–3428.

author keywords: Activity recognition; parallel transport; shape manifold; stationary incremental process; stochastic development
MeSH headings : Actigraphy / methods; Algorithms; Artificial Intelligence; Computer Simulation; Data Interpretation, Statistical; Humans; Image Interpretation, Computer-Assisted / methods; Models, Biological; Models, Statistical; Motor Activity / physiology; Reproducibility of Results; Sensitivity and Specificity; Whole Body Imaging / methods
TL;DR: This work effectively bridges the nonlinear modeling of human activity on a nonlinear space, with the classic stochastic modeling in a Euclidean space, and thereby provides a foundation for a more effective and accurate analysis of the non linear feature space of activity models.

High-Density SNP Genotyping of Tomato (Solanum lycopersicum L.) Reveals Patterns of Genetic Variation Due to Breeding

PLOS ONE, 7(9).

By: S. Sim*, A. Van Deynze*, K. Stoffel*, D. Douches*, D. Zarka*, M. Ganal, R. Chetelat*, S. Hutton* ...

MeSH headings : Breeding; Chromosome Mapping; Gene Frequency; Genome, Plant; Genotype; Linkage Disequilibrium; Solanum lycopersicum / genetics; Polymorphism, Single Nucleotide; Quantitative Trait Loci
TL;DR: The observed SNP variation and LD decay suggest that different patterns of genetic variation in cultivated tomato are due to introgression from wild species and selection for market specialization. (via Semantic Scholar)

Trading order for degree in creative telescoping

JOURNAL OF SYMBOLIC COMPUTATION, 47(8), 968–995.

author keywords: Definite integration; Hyperexponential terms; Zeilberger's algorithm
TL;DR: D degree bounding formulas are derived which allow to estimate the degree of the output equations from creative telescoping as a function of the order, and it is shown that equations of low order have high degree, and that higher order equations have lower degree. (via Semantic Scholar)
