Abstract:
Several agents capable of inducing vascular responses akin to those observed in inflammatory processes enhance the accumulation of nanoparticles in tumors. Exemplary vascular-active agents include a bacterium, a pro-inflammatory cytokine, and microtubule-destabilizing drugs. Such agents can increase the tumor to blood ratio of radioactivity by more than 20-fold compared to nanoparticles alone. Moreover, vascular-active agents dramatically improved the therapeutic effect of nanoparticles containing radioactive isotopes or chemotherapeutic agents.
Abstract:
The invention discloses a fabrication method for a surrounding gate silicon nanowire transistor with air as spacers. The method comprises: performing isolation, and depositing a material A which has a higher etch selectivity ratio with respect to Si; performing photolithography to define a Fin hard mask; etching the material A to form the Fin hard mask; performing source and drain implantation; performing photolithography to define a channel region and large source/drain regions; forming the Si Fin and the large source/drains; removing the hard mask of the material A; forming a nanowire; etching the SiO2 to form a floating nanowire; forming a gate oxide layer; depositing a polysilicon; performing polysilicon injection; performing annealing to activate dopants; etching the polysilicon; depositing SiN; performing photolithography to define a gate pattern; etching the SiN and the polysilicon to form the gate pattern; separating the gate and the source/drain with a space in between filled with air; depositing SiO2 to form air sidewalls; performing annealing to densify the SiO2 layer; using subsequent processes to complete the device fabrication. The invention is compatible with the CMOS process flow. The introduction of the air sidewalls can effectively reduce the parasitic capacitance of the device, and improve the transient response of the device, so that the method is applicable for a logic circuit with high performance.
Abstract:
The present invention relates to the discovery that, in human cancer, an 11q deletion of ATM together with an increase in ATR and CHEK1 expression correlates with resistance to ionizing radiation which could be overcome by inhibition of the ATR/CHEK1 pathway. It provides for methods of identifying patients unlikely to exhibit an adequate response to radiation therapy and/or chemotherapy who may benefit from ATR/CHEK1 pathway inhibition, as well as methods of treating said patients.
Abstract:
An embodiment of the present invention discloses a high speed uplink packet access adaptive retransmission method and apparatus. The method includes: obtaining a resource limitation state; performing adjustment decision according to the resource limitation state and a current target number of retransmissions of a UE; and adjusting the target number of retransmissions of the UE between a preset large target number of retransmissions and a preset small target number of retransmissions, where the large target number of retransmissions is greater than the small target number of retransmissions. The utilization rate of resources may be effectively improved.
Abstract:
EGFR biomarkers useful in a method for predicting the likelihood that a mammal that will respond therapeutically to a method of treating cancer comprising administering an EGFR modulator, wherein the method comprises (a) measuring in the mammal the level of at least one biomarker selected from epiregulin and amphiregulin, (b) exposing a biological sample from the mammal to the EGFR modulator, and (c) following the exposing of step (b), measuring in the biological sample the level of the at least one biomarker, wherein an increase in the level of the at least one biomarker measured in step (c) compared to the level of the at least one biomarker measured in step (a) indicates an increased likelihood that the mammal will respond therapeutically to the method of treating cancer.

Abstract:
Described is a technology by which a user interacts with a surface representative of a point cloud data to correct for imperfect scan data. The surface is reconstructed based on the interaction. Real time viewing of the image is facilitated by parallel surface reconstruction. For example, the user may draw strokes to reduce topological ambiguities in poorly-sampled areas. An algorithm automatically adds new oriented sample points to the original point cloud based on the user interaction. Then a new isosurface is generated for the augmented point cloud. The user also may specify the geometry of missing areas of the surface. The user copies a set of points from another point cloud, and places the points around the target area. A new isosurface is then generated.
