A radiation of Psylliodes flea beetles on Brassicaceae is associated with the evolution of specific detoxification enzymes.

Flea beetles of the genus Psylliodes have evolved specialized interactions with plant species belonging to several distantly related families, mainly Brassicaceae, Solanaceae, and Fagaceae. This diverse host use indicates that Psylliodes flea beetles are able to cope with different chemical defense metabolites, including glucosinolates, the characteristic defense metabolites of Brassicaceae. Here we investigated the evolution of host use and the emergence of a glucosinolate-specific detoxification mechanism in Psylliodes flea beetles.

Application of a cubic phase plate to a reflecting telescope for extension of depth of field.

Wavefront coding is an accepted technique to extend the depth of field in incoherent optical systems. We present the design of a reflecting telescope with wavefront coding by employing a cubic phase plate (CPP). We propose a method to reduce the CPP size by changing its position from the aperture stop to a secondary mirror without varying the point-spread function, which is insensitive to defocusing.

Miniaturized laser readout head for application in a double-wedge prism scanner.

Double-wedge prism scanners are typically used for one-dimensional (1D) scanning in imaging systems. This type of scanner operates on the principle of two identical wedge prisms counter-rotating around the optical axis with identical angular velocity in order to move the image formed by the optical system in the plane of detector arrays. However, the relationship between the deviation and rotation angles is not linear.
