Abstract: One or more embodiments herein can facilitate a process to guide a user at a digital medium. An exemplary system can comprise a memory that stores computer executable components, and a processor that executes the computer executable components stored in the memory, wherein the computer executable components can comprise an obtaining component that obtains user behavior data from a digital medium, the user behavior data defining an interaction of the user with the digital medium, a prediction component that, based on the user behavior data, predicts a path of the user within the digital medium, and a classification component that, based on the user behavior data and on the path prediction, classifies a position of the user along a defined path to a conversion objective of the digital medium. The conversion objective can comprise obtaining the user as a customer, achieving a financial transaction, or presentation of a communication.

Abstract: The present invention is directed to nanoparticles comprising chitosan and an antigen, whereby the chitosan has a degree of deacetylation of about 90% and a molecular weight from 5 kDa to 80 kDa, to microparticles containing such nanoparticles as well as to a process for preparation of such particles. The particles are usable for vaccination.

Abstract: The invention relates to a method for identifying T-cell stimulating protein fragments using the following steps: a) detecting the amino acid sequence of an antigen; b) subdividing the found amino acid sequence of the antigen into protein fragments; c) synthesizing at least one protein fragment; d) incubating a suspension containing t-cells with the protein fragments; e) identifying an induced T-cell cytokine or activation marker by flow-through cytometry, and; f) assigning the T-cells, with which T-cell cytokines and/or activation markers were identified, to the protein fragments which were incubated with the T-cells. The corresponding protein fragments/peptides are synthetically produced with the assistance of the detected positive sequence, and said corresponding protein fragments/peptides can be utilized to produce a medicament for immunostimulation.

Abstract: The invention relates to a method of peptide sequencing from peptide fragment mass data, wherein a plurality of candidate peptide sequences are determined comprises the steps of: calculating peptide fragment masses, searching a plurality of peak data for masses matching said calculated peptide fragment masses, annotating all permutations of said peak data with amino acid sequences that correspond to the calculated peptide fragment masses, extending said potential sequences to resulting masses with additional matching masses, extending stepwise additions until the resulting masses correspond to parental peptide masses or said parental peptide masses minus the mass of water, and identifying at least one peptide sequence by deleting sequences that can not be extended to endpoints of said parental peptide masses, and deleting identical sequences generated.

Abstract: The invention relates to a method of peptide sequencing from peptide fragment mass data, wherein a step of deriving a plurality of candidate peptide sequences comprises the following steps: calculating peptide fragment masses by adding to masses of a proton, hydronium ion, b1 ion or y1 ion masses of one amino acid or more amino acids; searching a plurality of peak data for masses matching said calculated peptide fragment masses; annotating in all permutations said peak data with amino acid sequences that correspond to said calculated peptide fragment masses, thereby creating one or more potential sequences; extending said potential sequences to resulting masses with additional matching masses by stepwise adding masses of one or more amino acids and searching for masses in said plurality of peak data that match said resulting masses; extending said stepwise additions until said resulting masses correspond to parental peptide masses or said parental peptide masses minus the mass of water, depending on whether t
