The present invention relates to a pyrazole amide derivative, pharmaceutical compositions containing this compound and to its use in therapy. The electrostatic chuck attracts and holds a substrate in a substrate processing apparatus that processes the substrate while generating optical energy. A photo detector detects a brightness and the brightness is thus controlled by the optical feedback from the photo detector. A user interface can present results in the form of browsing multiple hierarchical representations, wherein matching categories are differentiated from non-matching categories.
