Abstract: Techniques for warm cloning of computing nodes are provided. A request to clone a first computing node is received. Upon determining that a first transaction of a plurality of transactions is ongoing, a first moment in time when data associated with the first transaction was coherent on the first computing node is identified. Tracking data related to the first transaction is collected, beginning at the first moment in time. Further, a first storage associated with the first computing node is copied to a second storage associated with a second computing node, where the first transaction continues during the copying. The tracking data related to the first transaction is then transmitted to the second computing node.

Abstract: A method or system for supporting dynamic construction of a user selected sub-region (e.g., viewport or region of interest) from other sub-regions of a reference media presentation encodes reference media presentation as component tracks. A streaming decoder receives a streaming media file of the reference media presentation and displays an arbitrarily selected sub-region of the reference media presentation. The streaming media file has a derived track that (i) references one or more of the plurality of component tracks and (ii) specifies a set of operations for constructing media samples based on the media samples of the referenced component tracks. The streaming decoder provides media samples for the selected sub-region by retrieving the referenced component tracks and performing the set of operations specified by the derived track.

Abstract: A control device is used to adjust an output voltage of a voltage generator, and includes a master circuit, a slave circuit, and a power-scaling control circuit. The master circuit is coupled to a first bus. The slave circuit is coupled to a second bus. In a normal mode, the first and second buses are connected to each other via the power-scaling control circuit, the master circuit accesses the slave circuit via the first and second buses. In an adjustment mode, the power-scaling control circuit controls the master circuit to stop accessing the slave circuit, and the power-scaling control circuit adjusts the output voltage. When the master circuit sends a trigger signal, the power-scaling control circuit enters the adjustment mode. When the master circuit does not send the trigger signal, the power-scaling control circuit enters the normal mode.

Abstract: An electronic device such as a wristwatch may have a housing with metal portions such as metal sidewalls. The housing may form an antenna ground for an antenna. An antenna resonating element for the antenna may be formed from a stack of capacitively coupled component layers such as a display layer, touch sensor layer, and near-field communications antenna layer at a front face of the device. An additional antenna may be formed from a peripheral resonating element that runs along a peripheral edge of the device and the antenna ground. A rear face antenna may be formed using a wireless power receiving coil as a radio-frequency antenna resonating element or may be formed from metal antenna traces on a plastic support for light-based components.

Abstract: Disclosed herein are systems and methods for multidimensional and multi-relation sampling for implementing multidimensional two-sided interval joins. In an embodiment, a data platform receives query instructions for a two-sided N dimensional interval join, where N is an integer greater than 1. The two-sided N dimensional interval join has an interval-join predicate that compares intervals determined from the input relations in each of N dimensions. The data platform samples interval sizes in one or more input relations, and demarcates an N dimensional input domain based on the sampling. The data platform implements the two-sided N dimensional interval join using an N dimensional band join followed by a filter that applies the interval-join predicate. The N dimensional band join includes a hash join keyed to N dimensional domain cells overlapped at least in part by intervals in the input relations in each of the N dimensions.

Abstract: An analysis system may perform operations on an analyte that may be combined with multiple regents prior to being introduced into a flow cell. The instrument may include a volume into which the reagents to be combined with the analyte are aspirated one-by-one. The volume may be formed as a serpentine channel in a valve manifold associated with sippers for aspirating the reagents. The reagents may then be mixed by cycling a pump to move the reagents within the mixing volume or channel. For this, the reagents may be aspirated from a recipient into the volume or channel, ejected back into the recipient, and this process may be performed repeatedly to enhance mixing.
