Contextual geoanalytics engine in a data analytics system
Methods, systems, and computer storage media for providing a unified multilayer-based index for a contextual geoanalytics engine in a data analytics system. The contextual geoanalytics engine is configured to aggregate point-of-interest geographical data from multiple data sources into an aggregate or composite dataset. The contextual geoanalytics engine then transforms and maps the data into a homogenous dataset—i.e., a location embedding record that is homogenous representation of an aggregated dataset—comparable across global geographical regions. The homogenous dataset is accessible via the unified multilayer-based index that is a single geographical index, where the homogenous dataset is a composite of different datasets. The data includes different data types, where the data types are stored in different layers while sharing a common index (i.e., unified multilayer-based index). In this way, the unified multilayer-based index is a shared common index with a plurality of different layers associated with data used in geographically-based analytics. |

Methods and systems for solid phase peptide synthesis
Methods and systems for control of solid phase peptide synthesis are generally described. Control of solid phase peptide synthesis involves the use of feedback from one or more reactions and/or processes (e.g., reagent removal) taking place in the solid phase peptide synthesis system. In some embodiments, a detector may detect one or more fluids flowing across a detection zone of a solid phase peptide synthesis system and one or more signals may be generated corresponding to the fluid(s). For instance, an electromagnetic radiation detector positioned downstream of a reactor may detect a fluid exiting the reactor after a deprotection reactor and produce a signal(s). In some embodiments, based at least in part on information derived from the signal(s), a parameter of the system may be modulated prior to and/or during one or more subsequent reactions and/or processes taking place in the solid phase peptide synthesis system. In some embodiments, the methods and systems, described herein, can be used to conduct quality control to determine and correct problems (e.g., aggregation, truncation, deletion) in reactions (e.g., coupling reactions) taking place in the solid phase peptide synthesis system. |
