For a permutation π, let Sn(π) be the number of permutations on n letters avoiding π. Marcus and Tardos proved the celebrated Stanley-Wilf conjecture that L(π) = limn→∞ Sn(π) 1/n exists and is finite. Backed by numerical evidence, it has been conjectured by many researchers over the years that L(π) = Θ(k) for every permutation π on k letters. We disprove this conjecture, showing that L(π) = 2 Θ...

The management of landscapes for biological conservation and ecologically sustainable natural resource use are crucial global issues. Research for over two decades has resulted in a large literature, yet there is little consensus on the applicability or even the existence of general principles or broad considerations that could guide landscape conservation. We assess six major themes in the eco...

functions in landscape design include values in design and management process to satisfy moral and environmental needs that current attitudes see that as open space design by natural and man-made elements, while the basic intellectual layers related to human as the principles of environmental design have been forgotten. human urban knowledge seeks to meet in health, biological, psychological, s...

Ecological destruction in human-dominated landscapes has significant impacts on environment sustainability internationally. Landscape planning can play a role in mitigating the effects of human-related activities. One element of landscape planning involves the analysis of the biological, spatial and social arrangement of areas in an urban environment and identifying characteristics that are und...

Pyrenophora tritici-repentis is a necrotrophic fungus causal to the disease tan spot of wheat, whose contribution to crop loss has increased significantly during the last few decades. Pathogenicity by this fungus is attributed to the production of host-selective toxins (HST), which are recognized by their host in a genotype-specific manner. To better understand the mechanisms that have led to t...
