    摘要： Systems and methods for controlling fluid flow in an immersion lithography system. The system includes a fluid flow path that allows fluid to flow from a source through a fluid retention hood and then a fluid control valve. The system includes a pressure sensing system for determining a pressure drop across the fluid retention hood. The pressure drop across the fluid retention hood changes with the fluid flow rate. A control system receives signals indicating the pressure drop across the fluid retention hood and produces control signals for the fluid control valve. The control signals adjust the fluid flow rate through the fluid control valve to drive the flow rate to a desired rate, thereby driving the sensed pressure drop across the fluid retention hood to a desired pressure drop.

    摘要： A small percentage of cells within an established solid tumor have the properties of stem cells. These solid tumor stem cells give rise both to more tumor stem cells and to the majority of cells in the tumor that have lost the capacity for extensive proliferation and the ability to give rise to new tumors. Thus, solid tumor heterogeneity reflects the presence of tumor cell progeny arising from a solid tumor stem cell. We have developed a xenograft model in which we have been able to establish tumors from primary tumors via injection of tumors in the mammary gland of severely immunodeficient mice. These xenograft assay have allowed us to do biological and molecular assays to characterize clonogenic solid tumor stem cells. We have also developed evidence that strongly implicates the Notch pathway, especially Notch 4, as playing a central pathway in carcinogenesis.

    摘要： The present invention provides a liquid filtration device with internal flow paths that facilitate the purging of air bubbles from the device. The device includes internal channels that collect bubbles from fluid entering the filtration device and more efficiently direct fluid to sweep bubbles from the device during operation. The present invention also provides for an automatic means to minimize fluid loss during a vent process.
