Abstract: Systems and methods for time preserving full waveform inversion are disclosed. The methods may include acquiring, using a seismic acquisition system, a seismic dataset and, using a seismic processor, obtaining, from the seismic dataset, an event in two-way traveltime (TWT) and a velocity model in TWT, and converting the velocity model in TWT into a velocity model in depth. The methods further include producing a final velocity model in depth, where the final velocity model is produced using a full waveform inversion (FWI), the velocity model in depth, and a TWT-preserving method preserves the event in TWT at each iteration of the FWI; and forming a seismic image in depth using the final velocity model in depth and the seismic dataset. The methods further include identifying, using a seismic interpretation workstation and based on the seismic image in depth, a drilling target; and planning a borehole path to the drilling target.

Abstract: A hybrid heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The hybrid heart valve includes a substantially non-expandable, non-compressible prosthetic valve member having a peripheral sealing ring and an expandable stent frame projecting from an inflow end, thereby enabling attachment to the annulus without sutures. The stent frame may be plastically-expandable and may have a thin fabric layer covering its entirety as well as secondary sealing structures around its periphery to prevent paravalvular leaking. Other sealing solutions include interactive steps at the time of valve implant to establish seals around the stent and especially between the stent and the sealing ring of the valve member.

The computing resource may be configured to geographically reference the data layer fused with the 3D point cloud data of the agricultural geographic area, and generate a multi-layered data model for the geographically referenced data layer fused with the 3D point cloud data of the agricultural geographic area. A client device may be configured to selectively render the multi-layered data model.

Abstract: A head-mounted device may have an inner display that displays images for a user and an outer display that informs nearby people of the status of the user and inner display. For example, the outer display may display an image of a face, an abstract layer, or both, depending on whether the inner display is operating in passthrough mode, mixed reality mode, or virtual reality mode. An ambient light sensor in the head-mounted device may be used to measure the brightness and color of ambient light. The white point of the face layer on the outer display may be adapted to the color of ambient light, whereas the white point of the abstract layer on the outer display may remain fixed. The white point of a display may be a correlated color temperature setting (e.g., measured in degrees Kelvin) that determines the warmth or coolness of displayed colors.
