The present invention provides a system and method for detecting problems caused by access to incompletely initialized data storage in assembler and high-level language programs. Therefore, digital data reproduction performance is improved, and power consumption is reduced. These compounds and compositions find particular use in providing an abuse-resistant alternative treatment for certain disorders, such as attention deficit hyperactivity disorder, ADD, narcolepsy, and obesity. Preferred immunogens are peptides and preferred antigen binding proteins are antibodies. In one embodiment, a thickness of the compliant beam in a dimension perpendicular to the plane of the substrate is at least about 1.
