  • Publication number: 20240020275
    Abstract: A method for providing data immutability using a deduplication filesystem for data objects stored in the cloud by defining a protection duration from a first date to a fixed future date, and applying a retention lock to one or more data objects stored in cloud storage during the protection duration, the retention lock preventing deletion, modification or movement of the data objects by an unauthorized entity. The method defines a renew threshold date within the protection duration, and performs a garbage collection (GC) operation at the renew threshold date to permanently delete dead data objects and carry forward live data objects, and extends the retention lock on remaining live data objects and subsequently written data objects upon completion of the GC operation.

  • Publication number: 20230416145
    Abstract: The present disclosure relates to a visible light-catalyzed translucent concrete, and a preparation method and use thereof. The preparation method includes: extracting an iron oxide from a copper slag, mixing the iron oxide with TiO2 to obtain a photocatalyst, and then mixing the photocatalyst with an additive to obtain a photocatalytic slurry; preparing a concrete slurry using the copper slag after iron extraction as an aggregate; and pouring the photocatalytic slurry, the concrete slurry, and the photocatalytic slurry in sequence into a mold pre-laid with an optical fiber, to obtain the visible light-catalyzed translucent concrete. In the visible light-catalyzed translucent concrete, iron in the copper slag is used as a part of raw materials of the photocatalyst, and the copper slag after iron extraction is used as an aggregate to replace natural sand and gravel. This solves environmental pollutions caused by the copper slag and realizes resource utilization.

  • Publication number: 20230408407
    Abstract: An optical fiber multi-parameter sensing system and method are provided. The optical fiber multi-parameter sensing system comprises a light source, an optical circulator, a fiber-tip probe sensor and an optical spectrum analyzer, wherein the fiber-tip probe sensor can be placed into an analyte without changing the characteristics of the analyte. The variation of a bulk parameter that is a bulk refractive index of bulk environment around the fiber-tip probe sensor and a surface parameter which is a thickness of surface dielectric layer of the fiber-tip probe sensor can be determined simultaneously by monitoring the changing of resonance intensity and resonance wavelength of a single fiber-tip leaky mode resonance. The sensing system optionally configured such that multiple parameters in the analyte around the fiber-tip probe sensor can be obtained by detecting a single resonance peak.

  • Patent number: 11848232
    Abstract: Embodiments of the present disclosure relate to processes for filling trenches. The process includes depositing a first amorphous silicon layer on a surface of a layer and a second amorphous silicon layer in a portion of a trench formed in the layer, and portions of side walls of the trench are exposed. The first amorphous silicon layer is removed. The process further includes depositing a third amorphous silicon layer on the surface of the layer and a fourth amorphous silicon layer on the second amorphous silicon layer. The third amorphous silicon layer is removed. The deposition/removal cyclic processes may be repeated until the trench is filled with amorphous silicon layers. The amorphous silicon layers form a seamless amorphous silicon gap fill in the trench since the amorphous silicon layers are formed from bottom up.
