Abstract: The present invention relates to novel agonistic anti-TrkB antibodies and therapeutic and diagnostic methods and compositions for using the same.

Abstract: An air pipe for motor vehicles, in particular for connecting a hot component to a cold component, is provided. A first connector at a first end of the pipe is provided for securing the pipe in an airtight manner to a hot component and a second connector at a second end of the pipe is provided for securing the pipe in an airtight manner to a cold component. At least one flexible pipe portion is provided between the first and the second connectors. Supporting rings made from a material which is dimensionally stable in relation to the flexible pipe material are provided. The supporting rings surround a free pipe cross section and stabilize the cross-sectional shape of the flexible pipe portion.

Abstract: A device for detecting characteristics of a fluid, with a light source for emitting several light beams, of which one of the light beams is a measurement beam, which is provided for a passage through the fluid, and another light beam is a reference beam, which is provided for bypassing the fluid, with a movable cover device arranged downstream of the light source, which cover device is provided for covering the light beams and which is arranged so as to be transferable between a first position releasing the measurement beam and covering reference beam, and a second position covering the measurement beam and releasing the reference beam, and with a light detector arranged downstream of the cover device.

Abstract: A photonic apparatus includes a metamaterial resonator array overlying and electromagnetically coupled to a vertically stacked plurality of quantum wells defined in a semiconductor body. An arrangement of electrical contact layers is provided for facilitating the application of a bias voltage across the quantum well stack. Those portions of the semiconductor body that lie between the electrical contact layers are conformed to provide an electrically conductive path between the contact layers and through the quantum well stack.
