US Classification:

706 21, 706 30, 706925

Abstract:

A neural network based universal time series prediction system for financial securities includes a pipelined recurrent ANN architecutre having a plurality of identical modules to first adjust internal weights and biases in response to a first training set representing a nonlinear financial time series of samples of a financial quantity and a target value, and then determine and store an estimated prediction error of the ANN in order to adjust short time stock price predictions in accordance with the stored prediction error. The prediction system is also designed to output upper and lower prediction bounds within a confidence region.

Abstract:

A temperature-responsive hydrogel includes water, a poly(N-alkylacrylamide) copolymer of a first monomer and a second monomer that is different than the first monomer, and an adhesion-enhancing additive. One type of adhesion-enhancing additive is selected from the group consisting of Arg-Gly-Asp-Ser amino sequence (RGDS), 3-guanidinopropionic acid (GPA), manganese(II) chloride tetrahydrate, and combinations thereof. Characteristically, the temperature-responsive hydrogel has a failure pressure that is at least 2 times greater than a failure pressure for a base temperature-responsive hydrogel having the same composition without the adhesion-enhancing additive. Another type of adhesion-enhancing additive is selected from the family of plant polyphenols, and issued as a priming layer before deployment of the temperature-responsive hydrogel. It not only improves the adhesion of temperature-responsive polymer gels to biological tissues, but also reserves the thermal reversibility of the polymers.
