Abstract: This application relates to methods and apparatus for switching control of semiconductor switches. In a switching circuit, a semiconductor switch is implemented as a composite switch having a plurality of switch elements, each having a respective gate electrode. A switch driver is configured to drive the gate electrodes of the switch elements to a first gate voltage over a duration of a first switch transition and is configured to enable drive of at least some of the gate electrodes of the plurality of semiconductor switch elements at different times in a temporal sequence during the first switch transition. The temporal sequence is configured to provide an average resistance of the composite switch over the duration of the first switch transition which is closer to a final composite switch resistance, compared to driving the gate electrodes of the switch elements at the same time as one another.

Abstract: Strategies, systems, compositions, and methods for efficient production of knock-in cellular clones without reporter genes. An essential gene is targeted using a knock-in cassette that comprises an exogenous coding sequence for a gene product of interest (or “cargo sequence”) in frame with and downstream (3?) of an exogenous coding sequence or partial coding sequence of the essential gene. Undesired targeting events create a non-functional version of the essential gene, in essence a knock-out, which is “rescued” by correct integration of the knock-in cassette, which restores the essential gene coding region so that a functional gene product is produced and positions the cargo sequence in frame with and downstream of the essential gene coding sequence.

Abstract: A fire stop for use with a light fixture in a suspended ceiling or wall. It prevents flames and smoke from passing through the light fixture and spreading throughout a building by moving above the ceiling or behind the walls. The fire stop has a lightweight enclosure that defines an interior space disposed above the suspended ceiling, or behind the wall. Contained within the interior space are a portion of the light fixture and a layer of intumescent material. The intumescent material forms a material with a relatively low thermal conductivity that substantially fills the interior space, impeding the movement of flames or smoke, when the intumescent material reaches at least a pre-determined activation temperature.
