Abstract: As part of managing delivery of a given packet flow according to a reliable transport protocol, a sender sends, to a receiver, a last flow packet among multiple flow packets of a flowlet. After sending the last flow packet but before satisfaction of a timeout condition for the last flow packet, the sender sends one or more end-of-flowlet (“EOF”) packets, which can be flush packets, query packets, or another type of packet. The sender receives, from the receiver, feedback metadata for the EOF packet(s) and updates a tracking window based at least in part on the feedback metadata. The sender selectively resends one or more unacknowledged flow packets according to the updated tracking window. In this way, the sender can quickly address any dropped packets or significantly delayed packets at the end of a flowlet, without waiting for the timeout condition to detect the dropped or delayed packets.

Abstract: As part of managing delivery of a packet flow according to a reliable transport protocol that supports multi-path delivery, a sender splits data into multiple flow packets of a flow and sends at least some of the flow packets to a receiver on multiple paths of a network. The sender receives feedback metadata and updates an out-of-order (“OOO”) tracking window. The sender also determines a metric that quantifies degree of OOO delivery. In general, the metric measures the extent to which flow packets have been successfully delivered OOO after a “missing” flow packet. If a sufficient count or range of flow packets have been acknowledged as received OOO after the missing flow packet, the missing flow packet is likely to have been dropped—not merely delayed. Depending on the metric, the sender selectively resends to the receiver one or more unacknowledged flow packets.

Abstract: A method of writing data to a transparent substrate comprises forming a first voxel by focusing a first laser pulse on a first location in a transparent substrate; and forming a second voxel by focusing a second laser pulse on a second location in the transparent substrate. The first laser pulse and the second laser pulse have different amplitudes, resulting in the first and second voxels having different strengths. Also provided are a system useful for implementing the method; an optical data storage medium obtainable by the method; and a method of reading data from the optical data storage medium.

Abstract: A location-based augmented-reality system to generate and cause display of augmented-reality content that includes three-dimensional typography, based on a perspective, and location of a client device.

Abstract: This disclosure provides antibodies and antigen-binding fragments that can be administered to a subject that has been bitten by a venomous snake. Antibodies and antigen-binding fragments herein can be capable of treating or curing the subject and may provide protection against snake venom for up to several weeks. A combination or population of antibodies and antigen-binding fragments can be administered to the subject where the type of snake is not known or where a subject has been bitten by more than one species of snake. This disclosure further provides methods for identification of such broadly-neutralizing antibodies.

Abstract: The invention relates to a lens having an adjustable optical power comprising a container with a frame structure delimiting a lens volume and a reservoir volume, wherein the lens volume and the reservoir volume are fluidically connected and comprise a liquid, wherein both volumes have at least one opening that are laterally shifted to each other and wherein each opening is covered by two elastically deformable membrane portions, wherein in the space enclosed between the membrane portions for each opening another liquid enclosed in. The invention further teaches a piston structure that is arranged to adjust a pressure in the reservoir volume such as to control a focal strength of the lens volume.

Abstract: An occlusion detection system to perform operations that include: capturing image data that depicts an environment at a client device, the environment including a target object at a position within the environment; causing display of a presentation of the environment at the client device, the presentation of the environment including a display of the target object at the position within the environment; detecting a first attribute of the display of the target object at the client device; performing a comparison of the first attribute of the display of the target object and a second attribute associated with the target object; and detecting an occlusion based on the comparison.

Abstract: A vertical landing and take-off aircraft VTOL transitions from a vertical takeoff state to a cruise state where the vertical takeoff state uses propellers to generate lift and the cruise state uses wings to generate lift. The aircraft has an M-wing configuration with propellers located on the wingtip nacelles, wing booms, and tail boom. The wing boom and/or the tail boom can include boom control effectors. Hinged control surfaces on the wings, tail boom, and tail tilt during takeoff and landing to yaw the vehicle. The boom control effectors, cruise propellers, stacked propellers, and control surfaces can have different positions during different modes of operation in order to control aircraft movement and mitigate noise generated by the aircraft.
