In a multi-antenna communication system using LDPC codes, a simple method is used to effectively improve the received quality by performing a retransmittal of less data without restricting applicable LDPC codes. Also disclosed are methods of treating lesionous symptoms of a viral infection involving applying an effective amount of the anti-viral composition to the lesions. As a result, luminous efficiency of the OLED can be enhanced and a driving voltage can also be reduced. Control points not associated with a pin are scaled according to the canvas resizing. Each processor element then conforms the performance data to generate synchronized performance data which is then communicated to a performance monitoring application that requests the performance data from the logical processor. In one embodiment, electrodes are placed posterior and anterior in the region of the cervical vertebrae.
