Red dish mud-rich sed i ments are com mon in sev eral karst ar eas, in the form of red sur face soils and clastic cave in fill ings. The or i gin and sig nif i cance of red sur face soils have been much de bated over re cent years, while clastic mud-rich sed i ments in cave en vi ron ments have re ceived less at ten tion from geoscientists. The ge netic re la tion ship be tween these two ma te ...

Abstract. Ecosystems must now cope with climate change such as rising sea levels. These major changes have a direct impact on the coastal fringe. However, in recent years, ecosystems saltmarshes proven their adaptive capacity. Unmanned Aerial Vehicles (UAV) are an inexpensive and easily deployable alternative which offer us possibility to monitor these geomorphological ecological systems, been ...

A set of n triangles sharing a common edge is called a book with n pages and is denoted by Bn. It is known that the Ramsey number r (Bn) satisfies r (Bn) = (4 + o (1))n. We show that every red-blue edge coloring of Kb(4−ε)nc with no monochromatic Bn exhibits quasi-random properties when ε tends to 0. This implies that there is a constant c > 0 such that for every red-blue edge coloring of Kr(Bn...

A two-coloring of the vertices X of the hypergraph H = ( X , o °) by red and blue has discrepancy d if d is the largest difference between the number of red and blue points in any edge. A two-coloring is an equipartition of H if it has discrepancy 0, i.e., every edge is exactly half red and half blue. Letf(n) be the fewest number of edges in an n-uniform hypergraph (all edges have size n) havin...

Motivated by a crane assignment problem, we consider a Euclidean bipartite matching problem with edge-crossing constraints. Speci cally, given n red points and n blue points in the plane, we want to construct a perfect matching between red and blue points that minimizes the length of the longest edge, while imposing a constraint that no two edges may cross each other. We show that the problem i...

Case Description- A five-year-old Iranian cross-breed ewe with a dark red and soft mass on gingiva of mandibular region was presented to the Islamic Azad University of Tabriz Veterinary Medical Teaching Hospital. Macroscopically, a dark red, pedunculated, round-shaped and soft mass less than 1.5 centimeter on gingival compartment of right midlateral edge was observed. Temperature, heart rat...

We consider the following random process on the complete graph: repeatedly draw edges (with replacement) and with probability p assign the vertices of the edge blue and with probability 1 − p assign the vertices of the edge red. This is a random walk on a state space of red/blue colorings of the complete graph and so has a stationary distribution. We derive this stationary distribution as well ...

Sentinel-2 is planned for launch in 2013 and it is equipped with the Multi Spectral Instrument (MSI), which will provide images with high spatial, spectral and temporal resolution. It incorporates two new spectral bands in the red-edge region, which can be used to derive red-edge type of vegetation indices. These are particularly suitable for deriving estimates of canopy chlorophyll and nitroge...
