  • Publication number: 20140229957
    Abstract: The present invention provides a multi-core processor system, including: multiple central processor units and multiple groups of level-one hardware message queues. Each central processor unit is separately connected to a group of level-one hardware message queues and is configured to process messages in the level-one hardware message queues. Each group of level-one hardware message queues includes multiple level-one hardware message queues. Moreover, in each group of level-one hardware message queues, a level-one hardware message queue having a higher priority is scheduled preferentially, and level-one hardware message queues having the same priority are scheduled in a round-robin manner according to round robin scheduling weights. Through the multi-core processor system provided in the present invention, the efficiency and performance of the multi-core processor system are improved.

  • Publication number: 20140120165
    Abstract: A new particle morphology of glucocorticosteroids is described. The forms have a particle morphology that is particularly well suited for use in an inhaled corticosteroid drug suspension formulation for delivery from a next generation nebulizer device. Use of the new glucocorticosteroid particles enables enhanced drug delivery efficiency and increased residence time of the delivered drug in the lungs. New methods for producing glucocorticosteroid particles having these specific particle morphologies are also described. The methods provide a simplified, reproducible and scalable particle formation process that can produce glucocorticosteroid particles having a narrow particle size and shape distribution, a low surface energy, a low aspect ratio, uniform particle morphology and a reduced specific surface area.
