Abstract: The present disclosure provides a kit for identifying tumor tissue-of-origin, including an adapter and PCR amplification primers, where the adapter includes nucleotide sequences of A01-T, A01-B, A02-T, A02-B, A03-T, A03-B, A04-T, A04-B, A05-T, A05-B, A06-T, and A06-B; and the PCR amplification primers include nucleotide sequences of R01-F, R01-R, R02-F, and R02-R. In the present disclosure, new adapter nucleotide sequences and PCR amplification primers are designed, with higher accuracy and effectiveness. The present disclosure further provides a data analysis method for a kit for identifying tumor tissue-of-origin, including data preprocessing, alignment, methylation information statistics, quality control, and analysis. In the present disclosure, the analysis of a Beta value-based methylation index further improves a recognition ratio.

Abstract: The present disclosure provides a college admissions platform. The college admissions platform can have an application portal, a research request marketplace, an essay editing marketplace, and an essay sorter.

Abstract: The present disclosure provides a method, which may comprise obtaining a plurality of essay prompts, processing each essay prompt of said plurality of essay prompts using a natural language processing (NLP) algorithm to extract at least one feature from said each essay prompt and, using said at least one feature from said each essay prompt, generating two or more subsets of said plurality of essay prompts, wherein an essay prompt in a subset satisfies a measure of similarity with respect to each other essay prompt in said subset such that a single essay can be responsive to each essay prompt in said subset.
