Abstract: Examples of the disclosure are directed toward generating a causation score with respect to an agent and an outcome, and projecting a future causation score distribution. For example, a causation score may be determined with respect to a hypothesis that a given agent causes a given outcome, and the score may indicate the acceptance of that hypothesis in the scientific community, as described by scientific literature. A future causation score distribution, then, may indicate a probability distribution over possible future causation scores, thereby predicting the scientific acceptance of the hypothesis at some specific date in the future. A future causation score distribution can be projected by first generating one or more future publication datasets, and then determining causation scores for each of the one or more future publication datasets.

Abstract: Systems and methods for the efficient agitation of tissue samples. A device may include a plurality of chambers that each receives samples therein. The plurality of chambers may be uniformly spaced with respect to a least one dimension, to form a one dimensional or two dimensional array. Each of the chambers may include an opening and an agitator device in fluid contact with the sample disposed within the chamber. The agitator devices may include a micromotor which provides rotational motion to a shaft and an impeller fixed to the shaft such that the impeller and the shaft rotate together upon provision of the rotational motion by the micromotor. The system may include an electrical energy source electrically coupled to the plurality of micromotors to rotate the impellers sufficient to agitate the sample as required for a particular activity (e.g., homogenization, lysis).

Abstract: Oscillating angularly rotating a container containing a material may cause the material to be separate. Denser or heavier material may unexpectedly tend to collected relatively close to the axis of rotation, while less dense or light material may tend to collect relatively away from the axis of rotation. Oscillation along an arcuate path provides high lysing efficiency. Alternatively, a micromotor may drive an impeller removably received in a container. Lysing may be implemented in batch mode, flow-through stop or semi-batch mode, or flow-through continuous mode. Lysing particulate material may exceed material to be lysed or lysed material and/or air may be essentially eliminated from a chamber to increase lysing efficiency.

Abstract: There is provided an electrically-powered material-transport vehicle having a vehicle-charging contact on one side of the vehicle, and a second vehicle-charging contact on the opposite side of the vehicle. The vehicle has a load-bearing cap that covers the top of the vehicle, and a cap elevator for raising and lowering the cap. The cap can be raised and lowered to a transit position, a payload-engagement position, a charging position, and a maintenance position. In the transit position and payload-engagement position, the cap covers the vehicle-charging contacts so that they are not exposed. In the charging position, the cap is raised so that the vehicle-charging contacts are exposed. The vehicle can enter a charging-dock with the cap in the charging position in order to recharge the vehicle's battery.

Abstract: A delivery system for an implantable medical device includes an outer shaft and an inner shaft translatable within the outer shaft. An internally exposed coil is disposed within the inner shaft and is electrically coupled to an externally exposed coil that can be used to inductively transmit a current flowing through the internally exposed coil. An actuation member extends within the inner shaft and includes a coupler, a force translation rod that extends proximally from the coupler and a plurality of push pull rods that extend distally from the coupler and that releasably couple to the implantable medical device. As the force translation rod moves relative to the internally exposed coil, an impedance varies in accordance with relative position.

Abstract: An apparatus and method for sensing load current of an envelope tracking (ET) modulator enables load impedance of a power amplifier to be measured. Impairments associated with the load impedance characteristic can be suppressed by calibration and predistortion instead of by feedback (as done in the prior art). The ET modulator provides a switching regulator that can be reconfigured as a linear regulator for the purpose of sensing the load current. This allows the ET modulator to be operated open-loop, thereby eliminating the power consumption overhead resulting from utilization of a loop filter and error amplifier (used in the prior art) and achieving a higher overall efficiency.

Abstract: A collating station is disclosed for a machine intended to insert first and second documents into an envelope. Prior to the insertion operation, the first and second documents are advanced serially in a common plane. At a predetermined location, each first document is intercepted and lifted above the common plane and moved to a holding platform spaced above the common plane. The holding platform has a transverse terminal edge downstream from where the first document comes to rest. Thereupon, the first document resting on the holding platform and a following second document which continues to advance along the common plane as the first document travels toward the holding platform are advanced together in a parallel spaced relationship, toward a downstream station. As the documents are advanced, the first document drops off the terminal edge of the holding platform and onto the second document thereby completing the collating operation.

Abstract: A document collating and inserting system having displays for document count verification. A plurality of bank checks belonging to a check set are fed, counted and stacked at a stacking station while simultaneously an associated statement is fed to an imaging station where a number imprinted thereon is imaged by a video camera and displayed on a video monitor. The number represents a predetermined number which should equal the actual number of checks counted, the actual count also being displayed. An operator makes a visual comparison of the two displayed numbers and, if they are in agreement, initiates a cycle of the system thereby forming a collation of the statement and checks and transporting them to a holding station. From the holding station the collation is inserted within an envelope provided by an envelope feeder during the next cycle of the system. If the two numbers are not in agreement a mismatch switch is provided for the operator to activate before cycling the system.
