Abstract: Red rust staining of Al/Zn coated steel strip in “acid rain” or “polluted” environments can be minimised by forming the coating as an Al—Zn—Si—Mg alloy coating with an OT:SDAS ratio greater than a value of 0.5:1, where OT is the overlay thickness on a surface of the strip and SDAS is the measure of the secondary dendrite arm spacing for the Al-rich alpha phase dendrites in the coating. Red rust staining in “acid rain” or “polluted” environments and corrosion at cut edges in marine environments can be minimised in Al—Zn—Si—Mg alloy coatings on steel strip by selection of the composition (principally Mg and Si) and solidification control (principally by cooling rate) and forming Mg2Si phase particles of a particular morphology in interdendritic channels.

Abstract: A processing device in a memory sub-system traverses a plurality of management units of a memory device at a defined scan/read refresh frequency. For every management unit of the plurality of management units, the processing device identifies a page satisfying a lowest sensing overhead criterion, and senses data of the identified page without transferring the data out of the memory device.

For every management unit, the processing device identifies a page satisfying a lowest sensing overhead criterion, and senses data of the identified page without transferring the data out of the memory device.

Abstract: The disclosure provides for structured illumination microscopy (SIM) imaging systems. In one set of implementations, a SIM imaging system may be implemented as a multi-arm SIM imaging system, whereby each arm of the system includes a light emitter and a beam splitter (e.g., a transmissive diffraction grating) having a specific, fixed orientation with respect to the system's optical axis. In a second set of implementations, a SIM imaging system may be implemented as a multiple beam splitter slide SIM imaging system, where one linear motion stage is mounted with multiple beam splitters having a corresponding, fixed orientation with respect to the system's optical axis. In a third set of implementations, a SIM imaging system may be implemented as a pattern angle spatial selection SIM imaging system, whereby a fixed two-dimensional diffraction grating is used in combination with a spatial filter wheel to project one-dimensional fringe patterns on a sample.

Abstract: A computer vision dating system analyzes combinations of face features of the system's user's photographs and recommends potential dating partners. A user selects preferred and not-preferred faces from a sample of other user's pictures. The system analyzes the features of the preferred and not-preferred faces comparing the combinations of features in both categories with the features of other users in the database to find the users that most match the collective features preferred by the user. These pictures are presented to the user. Data from the user's profile input are analyzed to automatically generate the sample pictures from which the user selects his/her preferences. As the users are presented pictures after their sample selection, they can continue to select and reject pictures allowing the system to learn and refine the combinations of features and better locate those that most conform to a user's most preferred photo images.
