Abstract: Various embodiments relate generally to data science and data analysis, computer software and systems, and wired and wireless network communications to interface among repositories of disparate datasets and computing machine-based entities configured to access datasets, and, more specifically, to a computing and data storage platform to implement computerized tools to identify data classifications and similar subsets of graph-based data arrangements with which to join, according to at least some examples. For example, a method may include determining a classification type for a subset of data based on a graph data arrangement, generating presentation data as a first user input to detect selection of the first user input. The method may include predicting a classification type for data. The method may also include generating other presentation data configured to join datasets, such as a column of tabular-formatted data with one or more portions of a graph data arrangement.

Abstract: A system and method for operating a cryptocurrency, including generating, by first computing devices, raw data sets representative of activities performed by respective users while each of the users is using the Internet. A second computing device may determine an aggregate data value of at least a portion of an aggregate of the raw data sets. The at least a portion of the aggregate of the raw data sets being received from the users who contribute that portion of the raw data sets, the contributing users being data contributors. A basis value of a cryptocurrency as a function of the aggregate data value may be established. Total quantity of the cryptocurrency in circulation may be regulated as a function of the aggregate data value.

Abstract: A method for removing mercury and other related metals such as cadmium, zinc, copper, silver, from a liquid medium. This method comprises the step of contacting the liquid medium with an insoluble composition comprising an suitable insoluble carrier and a cysteine residue covalently fixed at the nitrogen atom thereof to the surface of the carrier.

Abstract: An insoluble composition for removing mercury from a liquid medium comprises a suitable insoluble carrier and a cysteine residue convalently fixed at the nitrogen atom thereof to the surface of the carrier.
