The accessory device comprises a connector tip that comprises a first wire segment and a second wire segment. The first and second wire segments are electrically conductive and electrically insulated from each other. The connector tip also comprises a first set of bristles and a second set of bristles. The first and second sets of bristles are electrically conductive. The first set of bristles is electrically connected to the first wire segment and electrically insulated from the second wire segment. The second set of bristles is electrically connected to the second wire segment and electrically insulated from the first wire segment. The first set of bristles is spaced sufficiently far from the second set of bristles as to prevent a short circuit between the first and second sets of bristles.

Abstract: A scalable periphery tunable matching power amplifier is presented. Varying power levels can be accommodated by selectively activating or deactivating unit cells of which the scalable periphery tunable matching power amplifier is comprised. Tunable matching allows individual unit cells to see a constant output impedance, reducing need for transforming a low impedance up to a system impedance and attendant power loss. The scalable periphery tunable matching power amplifier can also be tuned for different operating conditions such as different frequencies of operation or different modes.

Abstract: An apposition device having a first elongate element movably coupled with a second elongate element. The second elongate element is deployable distal to the structures to be apposed, in a position transverse to the first elongate element. The first elongate element may be pulled to pull the second elongate element to move the structures into apposition. A third element may be positioned proximal to the structures to hold the structures in apposition. The third element may be a ratcheting element fixable in place with respect to the first elongate element. The apposition device may be deployed with a fine gauge needle. The second elongate element may be deployed from a side port in the needle facilitating deployment, and/or movement of the second elongate element with respect to the first elongate element and into a deployment configuration. Such arrangement may allow control of the first elongate element independent of the needle.

The provided methods, compositions and uses include those involving the administration or use of one or more DGK inhibitors (DGKi) in a combination therapy with a T cell therapy, such as a genetically engineered T cell therapy involving cells engineered with a recombinant receptor, such as chimeric antigen receptor (CAR) or T cell receptor (TCR).

Abstract: Mobile management method, system and client. Method includes receiving a DNS query for a host name from an application on client; retrieving reputation data associated with host name from a local cache on client; and determining a policy based on host name and the reputation data. Based on determined policy for the host name, blocking attempted network flows to a host corresponding to host name to produce blocked attempted network flows. Method also includes sending attempted network flow metadata related to the blocked attempted network flows to a collector on client; transmitting the attempted network flow metadata from the collector to a VPN server pool via a VPN tunnel; and producing an anomaly report from the transmitted attempted network flow metadata. The anomaly report includes at least one of anomalies, cohorts, trends, location boundaries, detected network security issues, detected compromised clients and/or optimized network usage.

Abstract: A spiral wound membrane module is suitable for use with high temperature water that may also have a high pH, for example steam injection produced water. The module uses a membrane with a polyphenylene sulfide (PPS) backing material. The feed spacer of the module may be made from polyphenylene sulfide (PPS) or ethylene chlorotrifluoroethylene (ECTFE). The permeate carrier may be made of a woven nylon (i.e. nylon 6, 6) fabric coated with high temperature epoxy. The core tube and anti-telescoping device may be made of polysulfone. In some examples, the module may be used at a temperature of up to 130° C. Optionally, the module may be used at a pH of 9.5 or more. In a filtration method, the module may be operated at a pressure in the range of 150 to 450 psi. The module may be operated at a generally constant pressure.

Abstract: A system, method, and machine-readable storage medium for determining an amount of unique data in a distributed storage system are provided. In some embodiments, a combined efficiency set for a first data set stored in the distributed storage system, such as at a volume, may be generated. The first data set may include a first subset of data and a second subset of data in the distributed storage system. Additionally, a set of efficiency sets for the first subset of data may be generated. A set difference based on the combined efficiency set and the set of efficiency sets may be computed. An amount of memory used for storing unique data of the second subset of data may be estimated based on the set difference. The unique data may be present in the second subset of data but absent from the first subset of data.

Abstract: Systems and methods are described for a streamlined garbage collection process during which data integrity checking is also performed for a distributed key-value (KV) store utilized by a distributed storage management system. According to one embodiment, by making use of full or truncated block IDs (rather than an intermediate probabilistic data structure, such as a Bloom filter) for garbage collection, data integrity checking can be performed concurrently almost for free. During garbage collection, a block ID compare list is compared to block IDs within the distributed KV store. If a particular block ID is present in the distributed KV store but is missing from the block ID compare list, the corresponding data block represents garbage to be collected. If the particular block ID is present in the block ID compare list but missing from the distributed KV store, a data integrity error has been identified.
