Elements of photonic devices with high aspect ratio patterns are fabricated. A stabilizing catalyst that forms a stable metal-semiconductor alloy allows to etch a substrate in vertical direction even at very low oxidant concentration without external bias or magnetic field.

Encoding enhanced information into pixel channels
The disclosed techniques are focused on processes for encoding an enhanced image with non-image data. Notably, the “non-image data” is distinct from “image data” in that the image data defines display characteristics of an image (e.g., display properties of a pixel) while the non-image data is unrestricted and can describe any data, even data different than display characteristics. An image is accessed, where the image includes at least one pixel that is associated with at least one color channel. Non-image data is encoded into the color channel. An index, which maps where the non-image data has been encoded in the color channel of the pixel, is generated or modified. As a result of encoding the non-image data into the color channel, an enhanced image is generated. |

System and method for simultaneous consideration of edges and normals in image features by a vision system
This invention applies dynamic weighting between a point-to-plane and point-to-edge metric on a per-edge basis in an acquired image using a vision system. This allows an applied ICP technique to be significantly more robust to a variety of object geometries and/or occlusions. A system and method herein provides an energy function that is minimized to generate candidate 3D poses for use in alignment of runtime 3D image data of an object with model 3D image data. Since normals are much more accurate than edges, the use of normal is desirable when possible. However, in some use cases, such as a plane, edges provide information in relative directions the normals do not. Hence the system and method defines a “normal information matrix”, which represents the directions in which sufficient information is present. Performing (e.g.) a principal component analysis (PCA) on this matrix provides a basis for the available information. |

Imaging abnormalities in vascular response
Z maps combined with a standardized stimulus in the form of a targeted arterial partial pressures of carbon dioxide provide surprisingly enhanced images for the assessment of pathological CVR.

The object tracker is coupled with coded exposure of the image sensor, which modulates photodiodes in the image sensor with a known exposure function (e.g., based on the object tracking). This allows for motion blur to be encoded in a characteristic manner in image data captured by the image sensor. Then, in post-processing, deblurring is performed using a computational algorithm. |

Three-dimensional object reconstruction from a video
A three-dimensional (3D) object reconstruction neural network system learns to predict a 3D shape representation of an object from a video that includes the object.

Fair queuing of request tasks spawned by requests to execute generative operations
Fair queuing of request tasks spawned by requests to execute generative operations such as, for example, graph query language requests to execute a graph query language query, mutation, or subscription operations. Queuing techniques are used to prevent a heavy generative operation from dominating usage of computing resources of a host that executes many generative operations concurrently including a mix of heavy and normal generative operations. Generative operations are analyzed and classified as heavy or normal as the request tasks they spawn are being executed. If a generative operation is classified as heavy, then subsequent request tasks spawned by the heavy generative operation are added to an overload queue while request tasks spawned by concurrently executing normal generative operations as added to a main queue. For fairness, request tasks are polled from the main queue for execution at greater frequency than request tasks in the overload queue. |

Request manager framework

The techniques manage sequencing requests for different types of operations, such as backup and recovery operations, replication operations, migration operations, and so on, in a manner that avoids overwhelming storage node capacity. The techniques include receiving a sequencing request for an operation of a specified operation type at a request manager of a storage node and determining whether a capacity of the storage node is available for running the operation by a capacity manager for the specified operation type, in which the capacity manager is provided by a storage client and implemented on the storage node separate from the request manager. In this way, throttling, limiting, and/or prioritization requirements of the operation of the specified operation type can be defined by the storage client in a manner agnostic to the request manager. |

Non-disruptive migration of NVMe-of attached virtual volumes using log-based signaling and confirmation for cutover
A virtual volume (vVol) is non-disruptively migrated from a first data storage appliance (DSS) to a second DSS. In a synchronizing phase, data is copied from a source vVol to a destination vVol which is not mapped and to which a host computer has no path. Upon completion of synchronization, (1) a mapping is created to the destination vVol for the host and signaled to the host by sending a notification having an associated log page, (2) it is determined whether the host has retrieved the log page, (3) in response the host retrieving the log page, a cutover is performed making the destination vVol accessible to the host and the source vVol inaccessible to the host, and (4) in response to the host not retrieving the log page, the cutover is not performed, leaving the destination vVol inaccessible to the host computer (migration may be aborted or retried). |
