Computer-based methods that permit two or more users to perform simultaneous edits on a digitally encoded molecular structure. The methods use properties of conflict-free replicated data types (CRDT's) and causal trees to provide a distributed system which can manage the life-cycle of virtual molecular structures; including simultaneous editing, versioning, and provenance. Applications of the technology include, but are not limited to: simultaneous computer aided design of molecules in 2D or 3D in which users may be distributed across multiple computers and in which the need for computer time synchronization (offline or online editing) is obviated; version control and provenance tracking of a virtual molecule; and other types of data used in computer aided molecular design activities.

A method and system for diagnosing a condition of an engine is described herein. The method comprises obtaining a sample of lubricating fluid from the engine, filtering the sample to obtain a plurality of particles from the lubricating fluid, determining surface chemical compositions for the plurality of particles, comparing the surface chemical compositions to at least one reference chemical composition associated with corrosion of the engine, determining a level of corrosion of the engine based on the comparing, and diagnosing a condition of the engine based on the level of corrosion.

A method for improving an identification accuracy of mixture components by using a known mixture Raman spectrum is disclosed. After calculating a first similarity between a to-be-tested Raman spectrum characteristic vector group and a pure substance Raman spectrum characteristic vector group of an nth kind of pure substance in a Raman spectrum standard library, the method uses a known mixture library to calculate to obtain a second similarity between a to-be-identified substance Raman spectrum characteristic vector group and a spectral peak characteristic vector group with offset information corresponding to a pure substance in a known mixture, and determines a similarity between a to-be-tested mixture and the nth kind of pure substance according to the first similarity and all second similarities to thus obtain a component identification result. The present application uses the known mixture library to assist the Raman spectrum standard library in searching.

Devices including nematic liquid crystal-forming molecules are disclosed. The molecules include one or more dipoles and exist in a ferroelectric nematic state. Exemplary devices can further include an electrode for applying an electric field in, for example, and in-plane direction.

A method for characterising a solution S.sub.0 comprising a plurality of solutes, which comprises at least the steps consisting in: subjecting the solution S.sub.0 to a sequence of N successive rows of liquid-liquid extractions, this sequence leading to a total of [2.sup.(N+1)−1] different phases, 2.sup.N phases of which are issued from the last row N of partitions; acquiring experimental data by measuring an extensive and conservative quantity X in the 2.sup.N phases issued from the last row N of partitions of said sequence; and subjecting the experimental data to mathematical processing allowing to determine the distribution of the solutes of the solution S.sub.0, which contribute to the values of the quantity X obtained experimentally, according to various hydrophilicity/lipophilicity values.

The present disclosure describes a technology platform for creating and updating records of resources in a ledger. To create a record, a tenant organization may prepare a record to write to the ledger that may be flagged as temporary. Metadata may be added to the record, which flags the record as temporary. The metadata may comprise a unique code and an identification of a user that can approve the temporary record. The unique code and the identification may be sent, by the technology platform, to a device associated with one or more approving devices. Upon receiving the code and the identification of the transaction, the device may sign the unique code and invoke a routine based on the identification. The routine may fetch the temporary record. The device may compare the unique code to a code stored in the metadata of the temporary record. Upon valid verification of the unique code, the device may indicate authorization of the write. Based on the authorization, a proxy node associated with the technology platform may write a definitive record to the ledger based on the temporary record.
