Abstract: Disclosed is an ethylene-based polymer with a density from about 0.90 to about 0.94 in grams per cubic centimeter, with a molecular weight distribution (Mw/Mn) from about 2 to about 30, a melt index (I2) from about 0.1 to about 50 grams per 10 minutes, and further comprising sulfur from about 5 to about 4000 parts per million. The amount of sulfur is also determined based upon the total weight of the ethylene-based polymer. Also disclosed is process for making an ethylene-based polymer which includes the steps of splitting a process fluid for delivery into a tubular reactor; feeding an upstream process feed stream into a first reaction zone and at least one downstream process feed stream into at least one other reaction zone, where the process fluid has an average velocity of at least 10 meters per second; and initiating a free-radical polymerization reaction.

Abstract: A method for imparting to a general purpose (CISC), or reduced instruction set (RISC), type of central processing unit (CPU; microprocessor) the characteristics and performance of an integer arithmetic digital signal processor (DSP) which executes instructions acting upon multiple ("S") data elements in parallel. The method is applicable to all finite mathematical computations wherein product and sum terms (for example) will never overflow "1/S" fraction of total word width. "S" need not be a multiple of two, but the method is most useful when it is, such as in algorithms containing "butterfly" type computations. It may be used to advantage in the implementation of all discrete orthogonal transforms, and may be generalized to any size CPU word (e.g.: 16-bit, 32-bit, 64-bit, etc.) subject only to limits imposed by the range of vector spaces being handled.
