Using the nonlinear coherent states method, a formalism for the construction of the coherent states associated to ”inverse bosonic operators” and their dual family has been proposed. Generalizing the approach, the ”inverse of f -deformed ladder operators” corresponding to the nonlinear coherent states in the context of quantum optics and the associated coherent states have been introduced. Fina...

Several investigators have claimed that the retinal coordinates of corresponding points shift with vergence eye movements. Two kinds of shifts have been reported. First, global shifts that increase with retinal eccentricity; such shifts would cause a flattening of the horopter at all viewing distances and would facilitate fusion of flat surfaces. Second, local shifts that are centered on the fo...

The fungal pathogen Cronartium ribicola J.C. Fischer, causal agent of white pine blister rust (WPBR), was introduced to the eastern United States about 1898 (11). Hosts for the fungus include fiveneedle pines (Pinus sp. section Quinquefoliae) and currants and gooseberries (Ribes sp.). Natural infection of wild populations of Pedicularis bracteosa Benth and Castilleja Mutis ex L.f. have also bee...
