    Abstract: A method for predicting a reactant of a chemical reaction which results in a reaction product, such that a boundary condition is satisfied, is disclosed. The method comprises receiving records of molecule descriptions and related characteristic property values, generating training data for a machine-learning (ML) system for predicting a predefined characteristic property value of reaction products related to a reactant, and combining, for received records of the molecule descriptions, sub-structures of molecules described by the molecule descriptions using chemical rules to generate candidate reactants. Furthermore, the method comprises predicting, using the ML system, a predefined characteristic property value related to candidate reactants, whereby the candidate reactants are separately used as input for the trained machine-learning system, where the machine-learning system has been trained using the training data, and filtering out all candidate reactants for which a condition related to the predicted predefined characteristic property value is not met.

    Abstract: Provided are techniques for performing a search using a hypergraph. Entities are identified. A knowledge graph using the entities is generated, wherein nodes of the knowledge graph represent the entities and edges between the nodes represent pair-wise relationships, and wherein each of the edges carries an edge score that quantifies a degree of coherence between a pair of the entities. A hypergraph using the knowledge graph is generated, wherein nodes of the hypergraph represent the entities and hyperedges represent relationships between multiple entities, and wherein each of the hyperedges carries a hyperedge score that quantifies a degree of coherence between the multiple entities. A search request is received. A search result is generated using the hypergraph, wherein the search result comprises a set of coherently related entities. The search result is returned.

    Abstract: A device includes at least one tunable resistive element. Each tunable resistive element comprises a first terminal, a second terminal, and a dielectric layer arranged between the first and second terminals. The device is configured to apply at least one electrical set pulse to the resistive elements to form a conductive filament comprising a plurality of oxygen vacancies in the dielectric layer. The device is configured to apply at least one electrical reset pulse to displace a subset of the oxygen vacancies of the conductive filament. The at least one electrical reset pulse comprises a first part, which is adapted to increase the temperature of the conductive filament and increase the mobility of the oxygen vacancies of the conductive filament, and a second part, which is configured to displace the subset of the oxygen vacancies of the conductive filament.
