Abstract: A silole derivative is of formula (I): each of the groups in the above formula is defined as those in the description. The silole derivative of formula (I) has aggregation-induced emission performance, and is particularly applicable in luminescent parts and devices, fluorescent probes, biological imaging, lubricating oils and greases. A lubricating grease composition has photoluminescence performance, as well as one or more of advantageous anti-oxidation properties, anti-wear properties, extreme pressure properties and anti-rust properties. It is applicable in many mechanical equipment in electrical industry, metallurgical industry, food industry, paper industry, automobile industry and aircraft industry.

Abstract: The present invention discloses an etchant and an etching method for a copper-molybdenum film layer. The etchant includes a main etchant, and the main etchant includes hydrogen peroxide, a chelating agent, a first inorganic acid, and water. A mass percentage of the chelating agent in the main etchant is in a range of 2% to 10%, a mass percentage of the first inorganic acid in the main etchant is in a range of 1% to 10%, and a mass percentage of the hydrogen peroxide in the main etchant is in a range of 4% to 10%.

Abstract: A system and method for optimizing an objective having discrete constraints using a dataset, the dataset including a plurality of aspects associated with the objective. The method comprising: receiving the dataset, the objective, and constraints, at least one of the constraints comprising discrete values; receiving a seed solution comprising initial values for the at least the constraints; iteratively performing until a predetermined threshold is reached: determining a constraint space for each of the constraints have discrete values using a determination of a constraint satisfaction problem; determining an optimized value of the objective using an optimization model, the optimization model taking as input the dataset and the constraint space; and outputting the optimized objective.

Abstract: A method for sharing a mixed reality experience (mixed reality content, mixed reality event) between one or more computing devices is disclosed. The method includes: determining a spatial location and a spatial orientation (spatial data) of the one or more computing devices each having a camera; mapping the (spatial) location and/or the spatial orientation (spatial data) of each of the one or more computing devices into a mixed reality manager; and presenting an event that is shared among the one or more computing devices, and, the presenting of the event is experienced simultaneously and varies among each of the one or more computing devices depending on the location or the orientation or both.
