Abstract: Hypoxia plays a central role in cancer progression and resistance to therapy. A microdevice platform is engineered to recapitulate the intratumor oxygen gradients that drive the heterogeneous hypoxic landscapes in solid tumors. The microdevice design features a “tumor section”-like culture by incorporating a cell layer between two diffusion barriers, where an oxygen gradient is established by cellular metabolism and physical constraints. The oxygen gradient is confirmed by numerical simulation and imaging-based oxygen sensor measurement. Spatially-resolved hypoxic signaling in cancer cells is also demonstrated through immunostaining, gene expression assay, and hypoxia-targeted drug treatment. The microdevice platform can accurately generate and control oxygen gradients, eliminates complex microfluidic handling, allows for incorporation of additional tumor components, and is compatible with high-content imaging and high-throughput applications.

Abstract: This specification discloses a power polarization beam combiner and its applications in fiber communications. The power polarization beam combiner uses the photonic band gap formed in a photonic crystal to produce a left-hand material with a negative refractive index and high dispersion rate. Using such properties of the photonic crystal, several beams with different wavelengths and polarizations are combined and output to a common port.

Abstract: There is a need for adjustable capacitors for use in LC or RC matching networks in micro-circuits. This has been achieved by forming a set of individual capacitors that share a common bottom electrode. The areas of the top electrodes of these individual capacitors are chosen to be in an integral ratio to one another so that they can be combined to produce any capacitance within a range of unit values. For example, if four capacitors whose areas are in the ratio of 5:2:1:1, are provided, then any capacitance in a range of from 1 to 9 can be generated, depending on how the top electrodes are connected. Such connections can be hard-wired within the final wiring level to provide a factory adjustable capacitor or they can be connected through field programmable devices to produce a field programmable capacitor. A process for manufacturing the device is also described.

Abstract: A process for fabricating a CMOS device in which conductive gate structures are defined self-aligned to shallow trench isolation (STI), regions, without using a photolithographic procedure, has been developed. The process features definition of shallow trench openings in regions of a semiconductor substrate not covered by dummy gate structures, or by silicon oxide spacers located on sides of the dummy gate structures. Filling of the shallow trench openings with silicon oxide, and removal of the dummy gate structures, result in STI regions comprised of filled shallow trench openings, overlying silicon oxide shapes, and silicon oxide sidewall spacers on the sides of the overlying silicon oxide shapes. Formation of silicon nitride spacers on the sides of the STI regions, is followed by deposition of a high k gate insulator layer and of a conductive gate structure, with the conductive gate structure formed self-aligned to the STI regions.
