Approximate and exact solutions of intertwining equations through random spanning forests [PDF]
arXiv, 2017 For different reversible Markov kernels on finite state spaces, we look for families of probability measures for which the time evolution almost remains in their convex hull. Motivated by signal processing problems and metastability studies we are interested in the case when the size of such families is smaller than the size of the state space, and we ...

Journal of Systematics and Evolution, EarlyView.Phylogenetic relationships within Koeleriinae clades A and B are examined using DNA sequences of plastid rpl32‐trnL, rps16‐trnK, rps16 intron, and ITS regions. Phylogenetic analyses of different selected data sets yielded mostly congruent topologies in nuclear and plastid trees.

Intertwining wavelets or Multiresolution analysis on graphs through random forests [PDF]
arXiv, 2017 We propose a new method for performing multiscale analysis of functions defined on the vertices of a finite connected weighted graph. Our approach relies on a random spanning forest to downsample the set of vertices, and on approximate solutions of Markov intertwining relation to provide a subgraph structure and a filter bank leading to a wavelet basis

Genetic Mapping of the Powdery Mildew Resistance Gene Pm13 on Oat (Avena sativa) Chromosome 1D
Plant Breeding, EarlyView.ABSTRACT Powdery mildew, caused by the biotrophic fungus Blumeria graminis DC. f. sp. avenae, is a widespread disease of oats, especially in the temperate regions of Western and Central Europe, and the use of resistant varieties is the most sustainable way to ensure stable yields.

Estimating the inverse trace using random forests on graphs [PDF]
27th French Conference on Signal and Image Processing (GRETSI),
2019, 2019 Some data analysis problems require the computation of (regularised) inverse traces, i.e. quantities of the form $\Tr (q \bI + \bL)^{-1}$. For large matrices, direct methods are unfeasible and one must resort to approximations, for example using a conjugate gradient solver combined with Girard's trace estimator (also known as Hutchinson's trace ...

Variation in suppression of black‐grass by modern and ancestral cereal root exudates
Plant Biology, EarlyView.Root exudates of commercial and ancestral cereals inhibit black‐grass and are more consistent inhibitors than application of their constituent allelochemicals. Abstract This study aimed to determine the variability of hexaploid wheat (Triticum aestivum), ancestral diploid wheat (T.
