A method for decoloring 2-phenyl-3,3-bis(4-hydroxyphenyl)phthalimidine (“p,p-PPPBP”) is disclosed. The method comprises contacting a liquid solution containing p,p-PPPBP and the common impurities o,p-PPPBP and aminophenone with activated carbon fibers. The activated carbon fibers adsorb the impurities, resulting in a purified solution of p,p-PPPBP. The activated carbon fibers can then be regenerated, such as with a methanol solution having a highly basic pH.

An embodiment of a system and method for performing a numerical operation on input data in a hybrid floating-point format includes representing input data as a sign bit, exponent bits, and mantissa bits. The exponent bits are represented as an unsigned integer including an exponent bias, and a signed numerical value of zero is represented as a first reserved combination of the mantissa bits and the exponent bits. Each of all other combinations of the mantissa bits and the exponent bits represents a real finite non-zero number. The mantissa bits are operated on with a “one” bit before a radix point for the all other combinations of the mantissa bits and the exponent bits.

An embodiment of a method and a related apparatus for digital computation of a floating point complex multiply-add is provided. The method includes receiving an input addend, a first product, and a second product. The input addend, the first product and the second product each respectively has a mantissa and an exponent. The method includes shifting the mantissas of the two with smaller exponents of the input addend, the first product, and the second product to align together with the mantissa of the one with largest exponent of the input addend, the first product and the second product, and adding the aligned input addend, the aligned first product and the aligned second product.

Methods and a system are disclosed for a collaborate brainstorming interface that defines a collaboration session with a three dimensional holographic mind map. An intelligent agent guides a collaboration session that is structured by the interface. The intelligent agent detects key words, work flow steps and user interactions in the session to initiate searches that are filtered using artificial intelligence. The results are presented to developers interacting through the interface.

The present invention regards a variety of methods and compositions for obtaining epigenetic information, such as DNA methylation patterns, through the preparation, amplification and analysis of Methylome libraries. In particular, the method employs preparation of a DNA molecule by digesting the DNA molecule with at least one methylation-sensitive restriction enzyme; incorporating a nucleic acid molecule into at least some of the digested DNA molecules by either (1) incorporating at least one primer from a plurality of primers that have a 5′ constant sequence and a 3′ variable sequence, wherein the primers are substantially non-self-complementary and substantially non-complementary to other primers in the plurality; or (2) incorporating an oligonucleotide having an inverted repeat and a loop under conditions wherein the oligonucleotide becomes blunt-end ligated to one strand of the digested DNA molecule, followed by polymerization from a 3′ hydroxyl group present in a nick in the oligonucleotide-linked molecule; and amplifying one or more of the DNA molecules.
