Abstract: An acidizing plug assembly comprises a mandrel, sealing element, upper and lower backup rings, upper and lower cones, upper and lower slips each having teeth configured to engage a well casing, and a shoe. An external surface of the acidizing plug is configured to be acid-resistant, and one or more breakable plugs prevents acid from reaching an acid-vulnerable portion of the acidizing plug. The breakable plugs are broken when the acidizing plug is no longer needed to permit acid such as hydrochloric acid to dissolve at least a substantial portion of the acidizing plug.

Abstract: A system and method for distributing quantum entanglement using optically protected fiber optical paths is described. In some embodiments, multiple optical paths are used to connect a source site to a receiver site. Quantum entangled particles are transmitted from the source site to the receiver site using a first one of the multiple optical paths and related service channel information is transmitted from the source site to the receiver site using a second one of the multiple optical paths. In response to a failure of either the first or second optical path, an entanglement distribution controller automatically updates the routing such that the service channel information and the quantum entangled particles are routed concurrently on a remaining one of the first or second optical path.

Abstract: Systems and methods for coordinating and controlling vehicles, for example heavy trucks, to follow closely behind each other, or linking to form a platoon. In one aspect, on-board controllers in each vehicle interact with vehicular sensors to monitor and control, for example, gear ratios on vehicles. A front vehicle can shift a gear which, via a vehicle-to-vehicle communication link, can cause a rear vehicle to shift gears. To maintain a gap, vehicles may shift gears at various relative positions based on a grade of a road.

Abstract: Pairs of text collections are obtained. An individual pair comprises (a) a source text collection which includes a first group of text sequences and (b) an annotated analysis result of the source text collection, comprising a second group of text sequences and a set of evidence mappings generated by an evidence mapping model. An evidence mapping indicates, for a particular text sequence of the second group, another text sequence of the first group which provides evidence for the particular text sequence. A quality metric of the model is obtained using an automated evaluation methodology in which a question is generated from the particular text sequence, and an analysis of a pair of answers (including 10 an answer generated using an evidence mapping) to the question is performed. The quality metric is provided via a programmatic interface.

Abstract: A provider network implements service discovery and renaming. A provider network includes a domain name service (DNS) and a renaming tool. The DNS receives queries for service names and sends query logs to a data store. Each query log indicates the queried name and a network address (e.g., IP address). A user may request that the service be renamed to a new name. In response, the renaming tool adds a new entry to for the new name to the DNS. The renaming tool retrieves data from the query logs and identifies clients of the service. The renaming tool sends a notification to the identified clients that the name has changed to the new name. The renaming manger retrieves additional data from the query logs to identify how many of the clients have switched to using the new name. After enough clients have switched, the old name may be decommissioned.

The first message comprises a first estimate of a fidelity of entanglement between the first and second quantum elements, and a timestamp indicating a time associated with the first estimate. Based at least in part on the first message, a second estimate of a fidelity of the entanglement between the first and second quantum elements is generated, at a second time after the time indicated by the timestamp, and is compared to each of multiple thresholds. At least a first (second) action is performed in response to a result of comparing the second estimate to a first (second) threshold.

Abstract: In addition to word line related short circuits within the blocks of the array structure of a non-volatile memory device, such as NAND memory, word line related shorts can also occur in the routing for supplying the word lines of the memory blocks. Depending on the layout of the routing, some shorts for the word lines associated with one block can affect other blocks of the memory array. In particular, if the routing of a pair of adjacent local supply lines are adjacent to a global supply line, a short between the pair of adjacent local supply lines for one block can lead, through the global supply line, to defects in another of the block. Techniques are presented for detecting these layout related problematic word lines.

Abstract: An object storage system includes mass storage devices that implement general storage for objects stored in the object storage system and additionally includes other storage devices, such as solid-state drives, that provide higher performance storage access. The object storage system implements a common access interface for accessing both accelerated access objects (who are eligible to have cached copies stored on the higher performance storage devices) and non-accelerated access objects stored in the general storage. The cache is fully managed by the service and no changes are required for client applications to receive accelerated access to objects that are classified as accelerated access objects per a customer configurable acceleration policy for the object or for a bucket in which the object is stored.
