Abstract: An optical coupler in a photonic chip is configured to couple an optical port to an array of optical phase shifters in the chip. An optical amplifier module is optically coupled to a portion of the chip to receive phase shifted optical waves, and is configured to: provide, after propagation of the phase shifted optical waves through different respective gain regions, amplified optical waves that optically interfere with each other starting at an emission plane to form an optical phased array output beam, and provide an arrangement of the gain regions such that (1) at least two phase shifted optical waves propagating through adjacent gain regions have optical path lengths between the optical port and the emission plane that are substantially equal to each other, and (2) a pitch of the gain regions is substantially equal to a pitch of the amplified optical waves at the emission plane.

Abstract: Back end calls triggered by a user interaction with a client user interface may be identified. The user interaction may be correlated with a logic flow, and the logic flow may be associated with the back end calls. A supervised learning model may be trained using a labeled data set comprising the back end calls and their associated logic flow. Rules may be derived from the supervised learning model for classifying other back end calls. The rules may be outputted to a classifier that utilizes the rules to associate the other back end calls with the logic flow.

Abstract: A log event cluster analytics management method may involve storing a first portion of an entire cluster dictionary in a transient memory, storing at least a second portion of the entire cluster dictionary in a persistent database and comparing a new log event message to the first portion of the overall cluster dictionary. In response to not assigning the new log event message to any cluster in the first portion of the entire cluster dictionary in the transient memory, selecting a subset of clusters of the at least second portion of the cluster dictionary in the persistent database, comparing the new log event message to a cluster of the selected subset of clusters and assigning the new log event message to the cluster of the selected subset of clusters based upon the comparison.

Abstract: According to an example, an application code graph of an application may be received and the programming structures of the application may be ranked based on a ranking model. When the information regarding code changes associated with the application are received, the ranking model may be applied to the programming structures associated with the code changes. The impact of the code changes on the application performance may be determined and corresponding recommendations may be produced based on the determined impact.

Abstract: A method, executed by a processor, for generating a transaction classification rule that can be applied to unclassified transactions. The method includes receiving an identification of an existing unclassified transaction upon which the classification rule will be based; generating identification rules to identify subsequent unclassified transactions as similar to the existing unclassified transaction; generating the classification rule using the identified transaction; and storing the classification rule for application to the subsequent unclassified transactions. Application of the generated classification rule to the subsequent unclassified transactions produces transactions classified according to the classification rule.

Abstract: Certain novel formulations of plant growth media additives that act in such a manner as to permit proper amounts of moisture to contact root systems in order to reduce hydrophobicity within said media. The inventive formulation comprising multi-branched surfactant compounds with both hydrophobic and hydrophilic constituents within each branch attached to a polyfunctional base compound permit effective moisture penetration through plant growth media for sustained seedling and plant growth therein. Such multi-branched wetting agents provide sustained moisture penetration over a sustained period of time, since the individual branches of such compounds may become dissociated from its base polyfunctional compound. Since such branches include both hydrophobic and hydrophilic constituents themselves, and thus act as wetting agents, even after degradation of the initial surfactant compound, repeated wetting and moisture penetration, at least, are permitted.
