Abstract: Methods for reducing contact resistance include performing a selective titanium silicide (TiSi) deposition process on a middle of the line (MOL) contact structure that includes a cavity in a substrate of dielectric material. The contact structure also includes a silicon-based connection portion at a bottom of the cavity. The selective TiSi deposition process is selective to silicon-based material over dielectric material. The methods also include performing a selective deposition process of a metal material on the MOL contact structure. The selective deposition process is selective to TiSi material over dielectric material and forms a silicide capping layer on the silicon-based connection portion. The methods further include performing a seed layer deposition process of the metal material on the contact structure.

Abstract: A computer-implemented method for learning structural relationships between nodes of a graph includes generating a knowledge graph comprising nodes representing a system and applying a graph-based convolutional neural network (GCNN) to the knowledge graph to generate feature vectors describing structural relationships between the nodes. The GCNN comprises: (i) a graph feature compression layer configured to learn subgraphs representing embeddings of the nodes of the knowledge graph into a vector space, (ii) a neighbor nodes aggregation layer configured to derive neighbor node feature vectors for each subgraph and aggregate the neighbor node feature vectors with their corresponding subgraphs to yield aggregated subgraphs, and (iii) a subgraph convolution layer configured to generate the feature vectors based on the aggregated subgraphs. Functional groups of components included in the system may then be identified based on the plurality of feature vectors.

Abstract: Template based calendar events with graphic enrichment are provided. In some examples, upon receiving a request to create a calendar event, an event creation prompt may be presented. The prompt may include an event template selection element comprising visual aids, such as icons or emojis, that each represent different event templates for selection. Upon receiving a visual aid selection, information associated with the user requesting the calendar event may be retrieved based on the selected visual aid to infer one or more aspects of the requested event such as title, timing, and location. A suggested event with the inferred aspects may be presented to the user and upon receiving confirmation and/or modification, the suggested or modified event may be added to the user's calendar. Some events may be presented with a visual background such as an image or graphics on the calendar for prompt recognition.

Abstract: Disclosed are compositions and methods of ammonia removal in contaminated liquid and gas streams. The compositions may comprise water-soluble phosphonium compounds that react selectively with ammonia at ambient conditions to form covalent compounds. For liquid-phase treatment, the water-soluble phosphonium compounds may be dosed into the contaminated streams followed by pH adjustment using pH elevating compounds to form insoluble compounds. For gas-phase treatment, the water-soluble phosphonium compounds may be used either as scrubbing solution or as solid adsorbent obtained by impregnation into solid substrates to form solid scavengers, to selectively absorb and react with ammonia in a scrubber system.

The water-soluble and/or dispersible ferric hydroxide in a strong base may be introduced into a liquid stream to remove hydrogen sulfide. The water-soluble and/or dispersible ferric hydroxide may be further incorporated into a solid substrate for gas phase hydrogen sulfide removal.

Abstract: A methodology as described herein allows cyber-domain tools such as computer aided-manufacturing (CAM) to be aware of the existing information leakage. Then, either machine process or product design parameters in the cyber-domain are changed to minimize the information leakage. This methodology aids the existing cyber-domain and physical-domain security solution by utilizing the cross-domain relationship.
