Compared to other techniques of propagation, grafting is the most successful and feasible technique for asexual propagation of walnut plants. There is little information about graft union formation in walnut. Therefore, the objective of this study was to evaluate histological events during graft union formation in Juglans regia L. cv.

A ladder is a 2 × k grid graph. When does graph class $${\cal C}$$ exclude some as minor? We show that this the case if and only all graphs G in admit proper vertex coloring with bounded number of colors such for every 2-connected subgraph H G, there color appears exactly once H. This type relaxation notion centered coloring, where connected must be The minimum treedepth it known classes are th...

This paper evaluates the expected complementarity between the most prominent parts of the face for the gender recognition task. Given the image of a face, five important parts (right and left eyes, nose, mouth and chin) are extracted and represented as appearancebased data vectors. In addition, the full face and its internal rectangular region (excluding hair, ears and contour) are also coded. ...
