  • Publication number: 20230265091
    Abstract: This disclosure features chemical entities (e.g., a compound or a pharmaceutically acceptable salt, and/or hydrate, and/or cocrystal, and/or drug combination of the compound) that inhibit RNA polymerase I (Pol I). Said chemical entities are useful, e.g., for treating a condition, disease or disorder in which increased (e.g., excessive) Pol I activity contributes to the pathology and/or symptoms and/or progression of the condition, disease or disorder (e.g., cancer) in a subject (e.g., a human). This disclosure also features compositions containing the same as well as methods of using and making the same.

  • Publication number: 20130182729
    Abstract: In accordance with aspects of the present disclosure, a method is disclosed. The method includes controlling an operational wavelength of a wavelength tunable laser by receiving radiation from the laser at first photo-detector including a first optical element having a partially reflective coating on a front surface of the first optical element; receiving at least a portion of the radiation partially reflected from the front surface of the first optical element at an etalon; receiving radiation from the etalon at a second photo-detector including a second optical element having an anti-reflection coating on a front surface of the second optical element; determining, by processor, a control signal to be applied to the laser to control the operational wavelength of the radiation based on data from the first and the second photo-detectors; and transmitting the control signal to the laser to, control the operational wavelength of the radiation.

  • Publication number: 20130181339
    Abstract: A method and structure for mechanical self-alignment of semiconductor device features, for example multi-chip module features. Alignment of the features can be performed using mechanical alignment grooves within a layer of a first device and mechanical alignment pedestals of a second device. The alignment accuracy is limited by the patterning resolution of the semiconductor processing, which is in sub-micron scale. Flip-chip bonding can be used as the bonding process between chips to increase the alignment precision.

  • Patent number: 7823216
    Abstract: A method of producing a probe device for a metrology instrument such as an AFM includes providing a substrate having front and back surfaces and then forming an array of tip height structures on the first surface of the substrate, the structures having varying depths corresponding to selectable tip heights. The back surface of the substrate is etched until a thickness of the substrate substantially corresponds to a selected tip height, preferably by monitoring this etch visually and/or monitoring the etch rate. The tips are patterned from the front side of the wafer relative to fixed ends of the cantilevers, and then etched using an anisotropic etch. As a result, probe devices having sharp tips and short cantilevers exhibit fundamental resonant frequencies greater than 700 kHz or more.

  • Patent number: 7770231
    Abstract: A method and apparatus are provided that have the capability of rapidly scanning a large sample of arbitrary characteristics under force control feedback so has to obtain a high resolution image. The method includes generating relative scanning movement between a probe of the SPM and a sample to scan the probe through a scan range of at least 4 microns at a rate of at least 30 lines/sec and controlling probe-sample interaction with a force control slew rate of at least 1 mm/sec. A preferred SPM capable of achieving these results has a force controller having a force control bandwidth of at least closed loop bandwidth of at least 10 kHz.
