The present invention provides heterocyclic derivatives that modulate the activity of stearoyl-CoA desaturase. The flexible display apparatus includes: a display unit that displays an image and is flexible; and a sensor for detecting an approach of an object to a bent space of the display unit while the display unit is bent. As the preset time of the timer is reached, the movable unit will stop pushing the connecting mount, whereby it will bounce upward by a flexible restoring force, separating the leaves from the water again. Error correcting circuitry can further be designed to reduce static hazards. A determination is made as to which the participating computer devices will process the query by comparing the benefit values for the participating computer devices. In some aspects a TDLS persistent capable bit is stored at a computing device to indicate whether the computing device is capable of storing persistent group information associated with TDLS sessions.
