A CMOS image sensor is provided. The algorithm analyzes traffic load distribution in the wireless neighborhood and determines an optimum starting time of the CBP operation for the current user. The invention also provides methods for treating disorders associated with expression of HSPJ1 or HSPJ2. Data is recorded on four recording tracks of the two deep grooves and two lands between the deep grooves and the shallow groove. The content of said copolymer A which has a molecular weight of 800-7,000 and which has a molecular weight of greater than 70,000 are determined to account for 10 wt %-23 wt % and less than 5 wt %, respectively, based on the total weight of said copolymerA.
