    摘要： A method of producing a batch of a tetracycline-class component HPMC extended release pharmaceutical product having a desired dissolution profile, comprising: selecting a dissolution rate-controlling polymer comprising an HPMC component, the HPMC component having a selected % HP value; validating that the % HP in the selected HPMC component is such that a mean sample of the product complies with the desired dissolution profile over each time point in the dissolution profile, and preparing the product by preparing a formulation comprising a pharmaceutically effective amount of the tetracycline-class chemical and the selected HPMC component with the % HP value. There is also provided a method of predicting the dissolution rate profile over a number of dosage forms.

    摘要： High speed removal of material from a specimen employs a beam positioner for directing a laser beam axis along various circular and spiral laser tool patterns. A preferred method of material removal entails causing relative movement between the axis of the beam and the specimen, directing the beam axis at an entry segment acceleration and along an entry trajectory to an entry position within the specimen at which laser beam pulse emissions are initiated, moving the beam axis at a circular perimeter acceleration within the specimen to remove material along a circular segment of the specimen, and setting the entry segment acceleration to less than twice the circular perimeter acceleration.

    摘要： Preferred embodiments of the invention implement techniques for modifying the command trajectory, the architecture of a servomechanism control system, or both, to reduce the servo error during and/or after the command trajectory. An iterative refinement procedure generates for use by the servomechanism control system a corrective input, du, which significantly reduces the error between the desired and actual servomechanism control system outputs. In one embodiment, a uniquely identified plant model is employed in the iterative refinement procedure to compute an approximate gradient that improves the performance and reliability of the refinement procedure. In another embodiment, the actual plant response is used in place of the identified model in the iterative refinement procedure. This is accomplished by time-reversing the stored error signal from a training run, before applying it to the plant to generate an update to the corrective input signal du.
