Abstract: Medical dressings include a non-woven polymeric nanofiber mat embedded within a chitosan hydrogel matrix. The dressings may be obtained by electro spinning of polymeric nanofibers and thereafter incorporating a chitosan hydrogel into interstices of the mat by vacuum or positive pressure assistance. The resulting medical dressings may be optically transparent (e.g., at least about 50% up to about 95% light transmittance), flexible, and mechanically robust. The dressings may also incorporate self-adhesion promoters to allow self-adhesion to biological tissue, e.g., ocular surfaces, and/or therapeutic agents which are capable of delivering therapeutics (e.g. stem cells, drugs and the like) to the tissue surface. The dressings are especially useful as ocular bandages for the treatment and repair of ocular wounds.

Abstract: A method for task scheduling includes, if it is determined that there is an idle task scheduling token, causing a first computing resource in a computing system to acquire the idle task scheduling token as a first task scheduling token to execute a first task in a task queue.

Abstract: Aspects of the disclosure provide for a method of controlling an autonomous vehicle in an autonomous driving mode. For instance, a predicted future trajectory for an object detected in a driving environment of the autonomous vehicle may be received. A routing intent for a planned trajectory for the autonomous vehicle may be received. The predicted future trajectory and the routing intent intersect with one another may be determined. When the predicted future trajectory and the routing intent are determined to intersect with one another, a time gap may be applied to a predicted future state of the object defined in the predicted future trajectory. A planned trajectory may be determined for the autonomous vehicle based on the applied time gap. The autonomous vehicle may be controlled in the autonomous driving mode based on the planned trajectory.

Abstract: An anchor system with a bridle substrate and harness configured to attach to an anchor line. An outer bladder surrounds an inner bladder for coupling on top of the bridle substrate. Water enters the anchor system through a water inlet that feeds directly to the inner bladder and fills that first. Water then overflows from the inner bladder to the outer bladder to fill that second. The inner bladder provides stability and is positioned with a majority of its volume closer to an uphill end of the anchor bladder while the outer bladder is positioned with a majority of its volume closer to a downhill end of the anchor bladder. Reinforcement connectors for each bladder resist deformation of the bladders to resist movement of the anchor bladder while filling.

The first beam pattern may be associated with a wireless communication link to an object proximate to the first vehicle, which may be a second vehicle or a stationary object. Reconfiguring the first antenna may be further based on a steering angle associated with the first antenna and a distance between the first vehicle and the object proximate to the first vehicle.
