摘要： A quantization method for OFDM is described. In an embodiment, the method uses an objective function which is defined as a function of the quantization error of the OFDM signal in frequency summed over data subcarriers. A search algorithm is used to optimize the objective function and the solution found is quantized by rounding. The quantized value of the solution may then be fed back into the objective function to compute a value of that function and if the value is less than the value computed in a previous iteration of the method, the method is repeated using the quantized value of the solution as the new starting point for the search algorithm. If the value of the function is, however, not less than the value computed in a previous iteration, the new solution is discarded and the quantized value of the solution from the previous iteration is output.

摘要： The invention involves a papilloma pseudovirus that can induce immune response after oral intake as well as its preparation. It is characterized in that HPV or BPV pseudovirus are made by disrupting HPV-VLP or BPV-VLP, mixing them with plasmids (plasmids or DNA vaccine), and reassembling them into the pseudoviruses (VLPs with plasmids inside). Oral administration of the pseudoviruses will result in delivery to mucosal and systemic lymphoid tissues and induce immune responses for disease prevention and treatment. The pseudovirus induces stronger immune response than DNA vaccines. Additionally, the pseudovirus can be applied in gene therapy by bringing the therapeutic genes into lymphoid tissues in the human body.

摘要： A substrate for an LED assembly can have a plurality of cups formed therein. At least one cup can be formed within another cup. The cups can be co-axial with respect to one another, for example. A machined surface of the substrate can enhance reflectivity of the LED assembly. A transparent and/or non-global solder mask can enhance reflectivity of the LED assembly. A transparent ring can enhance reflectivity of the LED assembly. By enhancing reflectivity of the LED assembly, the brightness of the LED assembly can be increased. Brighter LED assemblies can be used in applications such as flashlights, displays, and general illumination.

摘要： A heat spreader for an LED can include a thermally conductive and optically transparent member. The bottom side of the heat spreader can be configured to attach to a light emitting side of the LED. The top and/or bottom surface of the heat spreader can have a phosphor layer formed thereon. The heat spreader can be configured to conduct heat from the LED to a package. The heat spreader can be configured to conduct heat from the phosphors to the package. By facilitating the removal of heat from the LED and phosphors, more current can be used to drive the LED. The use of more current facilitates the construction of a brighter LED, which can be used in applications such as flashlights, displays, and general illumination. By facilitating the removal of heat from the phosphors, desired colors can be better provided.
