Abstract: A computerized system and method of modeling myocardial tissue perfusion can include acquiring a plurality of original frames of magnetic resonance imaging (MRI) data representing images of a heart of a subject and developing a manually segmented set of ground truth frames from the original frames. Applying training augmentation techniques to a training set of the originals frame of MRI data can prepare the data for training at least one convolutional neural network (CNN). The CNN can segment the training set of frames according to the ground truth frames. Applying the respective input test frames to a trained CNN can allow for segmenting an endocardium layer and an epicardium layer within the respective images of the input test frames. The segmented images can be used in calculating myocardial blood flow into the myocardium from segmented images of the input test frames.

Abstract: A number of different sealed interfaces for power modules are described. In one example, a sealed interface includes a printed circuit board including a contact pad for power conduction to a bus bar of the printed circuit board, a semiconductor module including at least one power transistor, a terminal pin electrically coupled to the power module, and a housing for the power module. The housing includes an open terminal aperture that extends through the housing. The printed circuit board is seated upon the open terminal aperture, to close and seal the open terminal aperture, with the contact pad positioned within the open terminal aperture. The terminal pin contacts the contact pad of the printed circuit board within the open terminal aperture, and the open terminal aperture comprises a transitional feature to abate electric field intensity around an interface between the open terminal aperture and the printed circuit board.

Abstract: It is disclosed herein that RPE degeneration in human cell culture and in mouse models is driven by a non-canonical inflammasome pathway that results in activation of caspase-4 (also known as caspase-11 in mouse) and caspase-1, and requires cyclic GMP-AMP synthase (cGAS)-dependent interferon-? (IFN-?) production and gasdermin D-dependent interleukin-18 (IL-18) secretion. Reduction of DICER1 or accumulation of Alu RNA triggers cytosolic escape of mitochondrial DNA, which engages cGAS. Collectively, these data highlight an unexpected role for cGAS in responding to mobile element transcripts, reveal cGAS-driven interferon signaling as a conduit for mitochondrial damage-induced NLRP3 activation, and expand the immune sensing repertoire of cGAS and caspase-4 to non-infectious human disease. Coupled with the unexpected result that caspase-4, gasdermin D, IFN-?, and cGAS are elevated in the RPE of human eyes with geographic atrophy, these findings also identify new targets for a major cause of blindness.
