Abstract: Techniques described herein are used to support cross-platform data sharing, access, and management between a communication process flow management platform and a communication platform. Specifically, techniques described herein support a communication process flow management platform detecting an event associated with a communication process flow that control electronic communications between a tenant and a set of users. The platform may generate a data object corresponding to the event. The data object may include metadata associated with the event. The platform may transmit, to a communication platform, a request that includes the data object. The request may be configured to cause an entry associated with the event to be posted into the communication platform.

Abstract: Provided in some aspects are methods for light-controlled in situ surface patterning of a substrate comprising a step of blocking or ablating oligonucleotide molecules in a boundary region separating a plurality of spot regions, and attaching oligonucleotides to oligonucleotide molecules in a first one or more of the spot regions.

Abstract: A privacy-enable mobile phone case. The privacy-enabled case includes a privacy housing and a sliding element. The sliding element is slidingly coupled to the privacy housing and configured to secure a mobile device having one or more front facing camera(s), one or more rear facing camera(s), and one or more microphone(s). The one or more rear facing camera(s) and the one or more front facing camera(s) are covered when the sliding element is in a closed position by the privacy housing and cannot capture imagery, and the one more microphone(s) are covered in the closed position by the privacy housing thereby obstructing the recording of sound. The one or more rear facing camera(s) and the one or more front facing camera(s) are uncovered when the sliding element is in an open position and can capture imagery, and the one more microphone(s) are uncovered in the open position and can record sound.

Abstract: The present disclosure relates in some aspects to methods and compositions for manufacturing molecular arrays using a hybrid approach comprising using non-contact printing (e.g., using inkjet printing, slot die coating, and/or blade coating) and photolithography-guided oligonucleotide hybridization and ligation. In particular, the molecular arrays can be used for determining spatial patterns of abundance and/or expression of a biological target in a sample.

Abstract: Provided in some aspects are methods for light-controlled in situ surface patterning of a substrate. Compositions such as nucleic acid arrays produced by the methods are also disclosed. In some embodiments, a method disclosed herein comprises using photoresist for photocontrollable hybridization and/or ligation of nucleic acid molecules, wherein photoresist removal allows hybridization and/or ligation of nucleic acid molecules at the exposed area. A large diversity of barcodes can be created in molecules on the substrate via sequential rounds of light exposure, hybridization, and ligation.

Abstract: A sample holder includes a first member featuring a first retaining mechanism configured to retain a first substrate that includes a sample, a second member featuring a second retaining mechanism configured to retain a second substrate that includes a reagent medium, and an alignment mechanism connected to at least one of the first and second members, and configured to align the first and second members such that the sample contacts at least a portion of the reagent medium when the first and second members are aligned.

Abstract: An apparatus to increase a diameter of a well bore includes a drill pipe that includes a first end, a second end spaced apart from the first end, and a longitudinal axis. A first reamer is coupled to the drill pipe, the first reamer including a first plurality of teeth and a first reamer axis spaced radially apart from the longitudinal axis of the drill pipe. At least a second reamer is coupled to the drill pipe and spaced longitudinally apart from the first reamer. The at least a second reamer includes a second plurality of teeth and a second reamer axis spaced radially apart from the longitudinal axis of the drill pipe, the second reamer axis being angularly offset from the first reamer axis such that a drift diameter of the apparatus is smaller than a drill diameter of the apparatus.

Abstract: An apparatus to increase a diameter of a well bore includes a drill pipe and a first reamer and at least a second reamer. The second reamer is positioned diametrically opposed to the first reamer. A first plurality of cutting teeth are positioned about each of the first reamer and the at least a second reamer. A top of each successive tooth in a direction counter to a rotation of the apparatus in the well bore extends a radial distance from the longitudinal axis. Each tooth of the first plurality of cutting teeth is positioned at a different circumferential location about each reamer from any adjacent teeth of the first plurality of teeth. At least a second plurality of cutting teeth are positioned about each of the first reamer and the at least a second reamer, the at least a second plurality of cutting teeth being spaced longitudinally apart from the first plurality of cutting teeth.

Abstract: The present invention provides a method and apparatus for increasing the drift diameter and improving the well path of the well bore, accomplished in one embodiment by cutting away material primarily forming surfaces nearer the center of the drift, thereby reducing applied power, applied torque and resulting drag compared to conventional reamers that cut into all surfaces of the well bore.
