Publication number: 20240127906Abstract: This disclosure describes methods, non-transitory computer readable media, and systems that can use a computationally efficient model to determine a corrected methylation-level value for a specific sample nucleotide sequence. For instance, the disclosed systems determine a false positive rate and a false negative rate at which a given methylation sequencing assay converts cytosine bases. Based on the determined false positive rate and false negative rate, the disclosed systems determine a corrected methylation-level value that corrects for a bias of the given methylation sequencing assay.Type: ApplicationFiled: October 10, 2023Publication date: April 18, 2024Inventors: Qi Wang, Suzanne Rohrback, Sarah Shultzaberger, Rebekah Karadeema, Leslie Beh Yee Ming, James Baye, Colin Brown

Patent number: 11953264Abstract: A method of manufacturing ceramic tape includes a step of directing a tape of partially-sintered ceramic into a furnace. The tape is partially-sintered such that grains of the ceramic are fused to one another yet the tape still includes at least 10% porosity by volume, where the porosity refers to volume of the tape unoccupied by the ceramic. The method further includes steps of conveying the tape through the furnace and further sintering the tape as the tape is conveyed through the furnace. The porosity of the tape decreases during the further sintering step.Type: GrantFiled: August 29, 2023Date of Patent: April 9, 2024Assignee: Corning IncorporatedInventors: Michael Edward Badding, William Joseph Bouton, Jacqueline Leslie Brown, Timothy Joseph Curry, Roman E Hurny, Lanrik Wayne Kester, Thomas Dale Ketcham, John Albert Olenick, Kathleen Ritter Olenick, Jeremy Paananen, Thomas Silverblatt, Dell Joseph St Julien, Viswanathan Venkateswaran, Nathan Michael Zink

Patent number: 10967539Abstract: A manufacturing line includes a tape of green material that is directed through a furnace so that the furnace burns off organic binder material and then partially sinters the tape without the use of a setter board. Sintered articles resulting from the manufacturing line may be thin with relatively large surface areas; and, while substantially unpolished, have few sintering-induced surface defects. Tension may be applied to the partially sintered tape as it passes through a second furnace on the manufacturing line to shape resulting sintered articles.Type: GrantFiled: October 21, 2020Date of Patent: April 6, 2021Assignee: Corning IncorporatedInventors: Michael Edward Badding, William Joseph Bouton, Jacqueline Leslie Brown, Timothy Joseph Curry, Roman E Hurny, Lanrik Wayne Kester, Thomas Dale Ketcham, John Albert Olenick, Kathleen Ritter Olenick, Jeremy Paananen, Thomas Silverblatt, Dell Joseph St Julien, Viswanathan Venkateswaran, Nathan Michael Zink
