Abstract: Methods and systems for locking a cache line of a cache. A cache line is locked based on a count of a plurality of threads that access the cache line and maintained in the cache until all of the plurality of threads have loaded the cache line.

Abstract: Physical assistance for identification of an input location on a touchscreen may include detecting that a user has contacted a touchscreen at an initial touch point with a pointing device, predicting an input location from one or more input locations for receiving input on the touchscreen, determining a path from the initial touch point to the predicted input location, and generating a physical cursor on the touchscreen at a location proximate to the pointing device, wherein the physical cursor is a raised portion of the touchscreen.

Abstract: Techniques facilitating cached result use through quantum gate rewrite are provided. In one example, a computer-implemented method comprises converting, by a device operatively coupled to a processor, an input quantum circuit to a normalized form, resulting in a normalized quantum circuit; detecting, by the device, a match between the normalized quantum circuit and a cached quantum circuit among a set of cached quantum circuits; and providing, by the device, a cached run result of the cached quantum circuit based on the detecting.

Abstract: Implementing a hybrid classical-quantum neural network includes constructing, by at least a first processor, a neural network for classification of input data. The neural network includes a plurality of neural network components. The at least a first processor initiates training of the neural network using training data. The at least a first processor identifies one or more of the plurality of neural network components for replacement. A quantum processor constructs a quantum component corresponding to the one or more network components. The one or more identified neural network components of the neural network are replaced with the quantum component to construct a hybrid classical-quantum neural network.

Abstract: Mechanisms are provided for conducting a natural language dialogue between the automatic dialogue system and a user of a client computing device. An automatic dialogue system receives natural language text corresponding to a user input from the user via the client computing device, the natural language text having an ambiguous portion of natural language text. The automatic dialogue system analyzes user profile information corresponding to the user to identify an anomaly in the user profile information and predicts a user intent associated with the anomaly. The automatic dialogue system disambiguates the ambiguous portion of the natural language text based on the predicted user intent and generates a response to the user input based on the disambiguated natural language text which is output to the client computing device to thereby conduct the natural language dialogue.
