Abstract: The invention uses gel layers to cover and/or separate one or more aqueous reaction mixtures in a reaction vessel. A gel layer can protect reagents or reaction products from contacting the atmosphere. A gel layer can also separate multiple aqueous reaction mixtures so that they do not contact one another until the gel layer is broken. An oil layer can be inserted immediately underneath a gel layer. Gel layers can be penetrated by insertion of a tip from a micropipette to deliver a solution, such as a sample, below a gel layer. Micropipette tips or inert rods can also be used to disrupt gel layers resulting in mixing of aqueous reaction mixtures above and below a layer. Gel layers can also be broken by selective application of heat or movement of magnetic beads. Multiple gel layers separating multiple aqueous reagent mixtures can be broken in a defined sequence for an ordered series of bioprocessing steps.

Abstract: Systems and methods are provided for calculating, using an electronic processor, an average environmental brightness and determining a current pulse width modulation (“PWM”) output level provided to the light source. The method also includes determining, using the electronic processor, a target illumination level and a PWM adjustment rate. The PWM adjustment rate is based at least partially on the calculated average environmental brightness. The method also includes adjusting, using the electronic processor, the current PWM output level at the determined PWM adjustment rate to reach the target illumination level, and transmitting the adjusted PWM output level to the light source. The target illumination level is determined as a function of the current PWM output level and an output mode of the light source.

Abstract: According to implementations of the subject matter described herein, a solution for neural video coding is provided. According to the solution, estimated motion information of a target frame in a video, reference feature information and a reference reconstructed frame of a reference frame for the target frame are obtained. Context information for the target frame is determined using a context extraction model and based on the estimated motion information, the reference reconstructed frame, and the reference feature information. In a conversion between the target frame and a bitstream of the video, a reconstructed target frame of the target frame is generated using a frame coding model and based on at least the context information. In this way, richer context information can be extracted for coding and thus the coding efficiency can be improved.

Abstract: Various innovations facilitate the use of intra-picture prediction modes such as palette prediction mode, intra block copy mode, intra line copy mode and intra string copy mode by an encoder or decoder when wavefront parallel processing (“WPP”) is enabled. For example, for a palette coding/decoding mode, an encoder or decoder predicts a palette for an initial unit in a current WPP row of a picture using previous palette data from a previous unit in a previous WPP row of the picture. Or, as another example, for an intra copy mode (e.g., intra block copy mode, intra string copy mode, intra line copy mode), an encoder enforces one or more constraints attributable to the WPP, or a decoder receives and decodes encoded data that satisfies one or more constraints attributable to WPP.
