Arrangements to reduce charging damage in structures of integrated circuits. In one embodiment, a method of a server device includes automatically populating a hierarchy using a play-list history data associated with a media data of a client device and modifying the heirarchy based on a user override. The mesh structure can assume an expanded configuration for direct andor indirect application of thermal andor electrical energy to heat or otherwise electrically modulate neural fibers that contribute to renal function. The thermal energy storage system also includes a coolant circuit conveying a coolant therethrough. Also disclosed are various application features that may be implemented using the stored event data. The duct 34 defines the outer extremity of the path for gas andor air through the duct.
