Abstract: Microchannels in hydrogels play an essential role in enabling a smart contact lens. A wearable contact lens is disclosed herein that uses microchannels and connected chambers located in poly-2-hydroxyethyl methacrylate (poly(HEMA)) hydrogel that is used in a commercial contact lens with three-dimensional (3D) printed mold. The corresponding capillary flow behaviors in these microchannels were investigated. Different capillary flow regimes were observed in these microchannels, depending on the hydration level of the hydrogel material. In particular, it was found that a peristaltic pressure could reinstate flow in a dehydrated microchannel, indicating the motion of eye-blinking may help tear flow in a microchannel-containing contact lens. Colorimetric pH and electrochemical Na+ sensing capabilities were demonstrated in these microchannels. Micro-engineered contact lenses formed using poly(HEMA) hydrogel can be used for various biomedical applications such as eye-care and wearable biosensing.

Abstract: A method and system for finding and efficiently evaluating and selecting a wellbore path that accounts for placement rules and the presence of existing wells. A topological representation of the connected paths is created and managed. The topological representation may be generated as a pre-computed database of space information that represents the locations of existing wells and accounts for restrictions such as anti-collision and the parameters, including geological and drilling equipment parameters. Using such a representation, the design of a wellbore path may be completed quickly and more efficiently. The topology may represent all connected space for a section of the subsurface. This topological representation may be used to evaluate all possible paths from the starting point (surface location, tie-in point for a sidetrack, tie-in point for replanning, etc.) to the target and enable selecting the path that meets the conditions and is optimized for the existing constraints.

Abstract: Systems and methods for training and using a prompt token generator to generate a set of prompt tokens which, when fed into a pretrained generative image transformer (e.g., an autoregressive transformer, continuous diffusion model, non-autoregressive transformer, or discrete diffusion model), may bias the generative image transformer's output towards a particular domain (e.g., towards a particular class of images, towards a particular training instance, etc.). In some examples, the prompt token generator may be used to generate a set of different prompt token sequences, which may then be fed sequentially to a pretrained non-autoregressive generative image transformer as it iteratively generates each image in each time-step in order to introduce more diversity into the transformer's final output.

Abstract: This disclosure relates to a predictive lookahead system that generates simulated or predicted wellbore trajectory plans in a drilling environment and determines when a simulated wellbore trajectory plan is at risk based on various lookahead metrics, such as torque and drag (T&D) metrics and hydraulic pressure metrics. For instance, the predictive lookahead system uses a predictive framework with various steps to determine if drilling metrics for a predictive wellbore trajectory plan, such as T&D metrics and/or hydraulic pressure metrics corresponding to subsurface formations, may exceed one or more risk threshold limits and cause damage to the drill bit, drill string, casing, and/or surface rig. The predictive lookahead system determines whether a predictive wellbore trajectory, which aims to converge with a previously planned wellbore trajectory, can proceed safely along the projected trajectory without exceeding T&D, pressure window, or other lookahead metric limits in the wellbore.
