Abstract: A tool includes a housing, a drive assembly including an output shaft extending from the housing such that a tool element for performing work on a workpiece is attachable to the output shaft, and a bushing disposed within the housing. The bushing rotatably supports the output shaft. The bushing is impregnated with lubricant such that the bushing is self-lubricating, and the bushing has an impregnation ratio between about 5% and about 25%.

Abstract: Compositions and methods are provided for genome modification of a target sequence in the genome of a plant or plant cell, without incorporating a selectable transgene marker. The methods and compositions employ a guide polynucleotide/Cas endonuclease system to provide an effective system for modifying or altering target sites within the genome of a plant, plant cell or seed, without incorporating a selectable transgene marker. Once a genomic target site is identified, a variety of methods can be employed to further modify the target sites such that they contain a variety of polynucleotides of interest. Breeding methods and methods for selecting plants utilizing a guide polynucleotide/Cas endonuclease system are also disclosed. Compositions and methods are also provided for editing a nucleotide sequence in the genome of a cell, without incorporating a selectable transgene marker.

Abstract: Methods and apparatuses for analyzing and/or designing integrated circuits using virtual transparent cells disclosed. Some embodiments comprise calculating model values for virtual transparent cells or elements of an integrated circuit design varying a transparency variable in modeling equations, and allowing replacement of the cell with a wire based upon the calculations. Varying the value of the transparency value for the calculations may allow the virtual transparent cells to be continuously modeled between a wire and a conventional version of the cell. Some embodiments may comprise a cell library with one or more modeling formulas for one or more virtual transparent cells and a response module to calculate different model values of the modeling formulas.
