Abstract: A data storage device and a method of operating same are provided. The method includes: based on identifying that first data stored in a first erasing and writing unit is to be moved, identifying a second erasing and writing unit as a destination for the first data; and moving the first data from the first erasing and writing unit to the second erasing and writing unit, wherein a life cycle of second data stored in the second erasing and writing unit is the same as a life cycle of the first data stored in the first erasing and writing unit.

Abstract: This application describes a rendering method and apparatus, a device, and a storage medium. The method comprises: determining a texture element in a to-be-rendered scene, and determining a target spatial directional tree corresponding to the to-be-rendered scene. The target spatial directional tree represents an incident ray distribution corresponding to the texture element in the to-be-rendered scene. The method further comprises determining, based on the target spatial directional tree, a scene spatial region for the texture element, determining the incident ray distribution corresponding to the texture element based on a quantity of light paths and light energy in the scene spatial region; and determining a light rendering result corresponding to the texture element based on an incident ray corresponding to the incident ray distribution.

Abstract: The present invention relates to a solar azimuth estimation method and system based on multi-channel feature enhancement and region-aware attention, belonging to the technical field of intelligent navigation for low-altitude economy unmanned systems. Aiming at the problem of decreased accuracy in solar azimuth estimation based on polarization images under complex cloud cover conditions, the present invention proposes a deep learning framework integrating multi-channel features and direction-aware attention. First, based on polarization light field information acquired by a division-of-focal-plane polarization camera, a three-channel composite input feature composed of a polarization intensity map, an adaptive threshold gradient map, and high-frequency residual edge information is constructed.

Abstract: Embodiments provide a multi-cone X-ray imaging Bragg crystal spectrometer for spectroscopy of small x-ray sources with a well-defined spectral resolution. The spectrometer includes a glass substrate machined to a multi-cone form; and a thin crystal slab attached to the glass substrate, whereby the multi-cone X-ray imaging Bragg crystal spectrometer provides rotational symmetry of a ray pattern, providing for accurate imaging, for each wavelength in the spectral range of interest. One or more embodiments include a streak camera and/or a gated strip detector.

Abstract: A system/apparatus and a positioning method for the determination of the delivery of protons within a mammalian body or inanimate medium, as well as a treatment method which comprises the delivery of protons to a mammalian body. The system/apparatus necessarily comprise the use of a detector which is placed in the proximity of the body or medium which is responsive to a signal emitted from a fiducuial marker which his positioned within or in the near proximity of target tissue within the body or target volume within the medium. A signal emitted from the fiducial marker is responsive to the impingement of protons thereon received from a controlled proton beam, the signal may be used to modify the subsequent operative characteristics of the source of protons.
