Crude aqueous and methanolic extracts of 97 plant species belonging to 35 families collected from the west of Iran were screened for antifungal activity against economically important phytopathogenic fungi, Pythium aphanidermatum. Bioassay of the extracts was conducted by paper disc diffusion method on agar plate cultures with four replications. Seventeen of 97 (17.5%) plant species showed inhi...

Information fusion has a potential applicability to a multitude of different applications. Still, the JDL model is mostly used to describe defense applications. This paper describes the information fusion process for a robot removing weed in a field. We analyze the robotic system by relating it to the JDL model functions. The civilian application we consider here has some properties which diffe...

An important challenge in the analysis of mechanochemical coupling in molecular motors is to identify residues that dictate the tight coupling between the chemical site and distant structural rearrangements. In this work, a systematic attempt is made to tackle this issue for the conventional myosin. By judiciously combining a range of computational techniques with different approximations and s...
