Abstract: A thermal accelerant is delivered to a tissue site and localized to modulate the shape, extent or other characteristic of RF or microwave-induced hyperthermic tissue ablation. The accelerant may be provided via an image-guided hand piece or via a lumen added to a microwave antenna, and promotes faster heating, more complete ablation and/or a more extensive treatment region to reduce recurrence of treated cancers, overcoming natural limitations, variations in tissue response and drop-off or thermal loss away from the antenna. The accelerant is delivered as a viscous but heat sensitive fluid, and is fixed in place to provide regions of preferential absorption or heating. Shorter exposure times to heat the far field may allow survival of vulnerable tissue such as vessels, and multiple antennae may be used for effective treatment of irregular or large tumors.

Abstract: The present disclosure generally relates to mass spectrometers, including but not limited to mass spectrometers able to emit ions at determinable times. In some aspects, the time between when ions leave an ion source and the time the ions reach a detector may be determined at a relatively high time resolutions, which may be useful for certain applications such as sequencing of biopolymers. In addition, in some cases, a relatively high number of ions leaving an ion source may be determined at a detector, e.g., at least 50% or more of the ions that are produced. Other aspects are generally directed to systems and methods for using such mass spectrometers, techniques involving such mass spectrometers, or the like.

Abstract: There is disclosed an extractor (10) for extracting an elongate body (12) from the ground. The extractor (10) includes a holding assembly (14) operatively adapted to hold the elongate body (12) to be extracted from the ground and a guide assembly (24) operatively associated with the holding assembly (14). The guide assembly (24) includes (i) a guide follower (26) for operative attachment to the holding assembly (14), and (ii) a guide (28) along which the guide follower (26) is caused to move when the elongate body (12) is extracted from the ground. The extractor (10) further includes a drive assembly (30) operatively associated with the guide follower (26). The drive assembly (30) is adapted to be coupled with a hand tool for applying torque to the drive assembly (30). Applying torque to the drive assembly causes the guide follower (26) to move along the guide (28) thereby to extract the elongate body (12) from the ground.
Abstract: A system for processing a selected feedstock using a catalyst includes a reactor, a catalyst recovery system, and a conduit. The reactor receives the catalyst and the selected feedstock. A reaction between the selected feedstock and the catalyst generates a spent catalyst. The catalyst recovery system processes the spent catalyst. The conduit connects the reactor to the catalyst recovery system and has a lateral section. The spent catalyst flows from the reactor through a flow space defined by an inner wall of the lateral section to the catalyst recovery system. The system also includes a fluidizer positioned at the lateral section. The fluidizer includes at least one nozzle. The at least one nozzle is completely inside the flow space. The at least one nozzle forms and directs a jet of a fluidizing agent into the spent catalyst in the lateral section.

Abstract: A motion planner of an autonomous vehicle's computer system uses reconfigurable collision detection architecture hardware to perform a collision assessment on a planning graph for the vehicle prior to execution of a motion plan. For edges on the planning graph, which represent transitions in states of the vehicle, the system sets a probability of collision with a dynamic object in the environment based at least in part on the collision assessment. Depending on whether the goal of the vehicle is to avoid or collide with a particular dynamic object in the environment, the system then performs an optimization to identify a path in the resulting planning graph with either a relatively high or relatively low potential of a collision with the particular dynamic object. The system then causes the actuator system of the vehicle to implement a motion plan with the applicable identified path based at least in part on the optimization.
