In auctioning items, pseudo bids are determined based on the bid price and auction budget submitted by a bidder. The bid associated with the highest pseudo bid is identified as the winning bid. A consistent pseudo bid function is applied to determine the pseudo bids for each of the bids, or a variable pseudo bid function is selectively applied to some bids. The pseudo bid increases with increased bid prices and/or increased auction budgets. When a winning bid is identified, the winner's auction budget is debited the price of the item won, and the pseudo bid is recalculated using the remaining auction budget. Bidders submitting higher auction budgets are rewarded by being able to win more items because their auction budgets increase their pseudo bids. Recalculating pseudo bids based on remaining auction budgets allows different bidders to alternately win successive rounds as previous winners'auction budgets are reduced.

An audio encoder and decoder use architectures and techniques that improve the efficiency of quantization (e.g., weighting) and inverse quantization (e.g., inverse weighting) in audio coding and decoding. The described strategies include various techniques and tools, which can be used in combination or independently. For example, an audio encoder quantizes audio data in multiple channels, applying multiple channel-specific quantizer step modifiers, which give the encoder more control over balancing reconstruction quality between channels. The encoder also applies multiple quantization matrices and varies the resolution of the quantization matrices, which allows the encoder to use more resolution if overall quality is good and use less resolution if overall quality is poor. Finally, the encoder compresses one or more quantization matrices using temporal prediction to reduce the bitrate associated with the quantization matrices. An audio decoder performs corresponding inverse processing and decoding.

The second recording layer is formed with a dye mixture of cyanine dye and imonium dye having relations Wa>Wb and na>nb, in which Wa and Wb are a mass of the cyanine dye and the imonium dye, respectively, and “na” and “nb” are refractive indices of the cyanine dye and the imonium dye, respectively, to the laser beam having a specific wavelength, and having a relation na−nc>0.1 in which “nc” is a refractive index of the dye mixture.

Easy starting rolls of perforated tissue product which have a reduced tendency to ply separate are formed with an adhesively secured doubled over tail tab folded against the roll. The strength and location of the bonds are controlled by controlling the penetration of the adhesive into the tissue. The dry tensile strength of the projecting folded over tail tab exceeds 400 g/in and the caliper thereof exceeds one mil The adhesive bonds are spaced away from lines of perforation joining sheets in the initial sheets of the roll.
