  • Publication number: 20250092511
    Abstract: A vapor deposition system is described. The vapor deposition system includes a reaction chamber and a reactant delivery subsystem coupled with the reaction chamber. The reaction chamber is configured to retain a substrate therein. The reactant delivery subsystem includes inlets, a pre-reaction region, and outlets. The inlets receive precursors and chalcogen precursor(s). The pre-reaction region is configured to receive the precursors from a portion of the inlets and to react at least a portion of the precursors to form modified precursor(s). The modified precursor(s) are more thermally stable than metal-containing precursor(s) of the precursors used to form the modified precursor(s). The outlets are coupled with the reaction chamber and the pre-reaction region. The outlets separately provide the modified precursor(s) and the chalcogen precursor(s) to the reaction chamber. The modified precursor(s) and the chalcogen precursor(s) react and form a chalcogen film on the substrate in the reaction chamber.

  • Publication number: 20250078444
    Abstract: The present invention provides a method and system for multi-modal remote sensing image hybrid matching with multi-dimensional oriented self-similarity features. The method comprises: hybrid feature coarse matching is executed by rapidly extracting the image's self-similarity features using the offset mean filtering method and describing the feature points using the directional information of the self-similarity features. Through this coarse matching, an affine transformation model between multi-modal images is estimated, and an initial affine transformation is applied to the matched image. Next, the multi-dimensional oriented self-similarity feature fine matching is performed by constructing multi-dimensional oriented self-similarity template features using the multi-channel self-similarity map obtained from the hybrid feature coarse matching stage.

  • Publication number: 20230001717
    Abstract: Techniques for determination of size of printable medium are described. In an example, a printing device includes an adjuster that is movable based on a size of a printable medium to be fed to the printing device. A first element is coupled to the adjuster and moves with the adjuster to indicate a position of the adjuster. A second element is movable relative to the adjuster. A position signal indicative of a distance between the second element and the first element is generated. The position signal can be used to determine the size of the printable medium.

  • Patent number: 11085936
    Abstract: A method and kit the simultaneous analysis of thyroid hormones (THs) and related metabolites in serum are disclosed. The method includes the extraction of THs and related metabolites, the derivatization of THs and related metabolites with 5-N-succinimidoxy-5-oxopentyl)triphenylphosphonium bromide (SPTPP), and the analysis of SPTPP derivatives using ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Free or total THs (T3 and T4) together with their related metabolites (MIT, DIT, T0, T1, rT1, 3,3?-T2, 3,5-T2, and rT3) can be determined simultaneously, rapidly, and accurately. This invention overcomes the limitation that the traditional method can only be used for the analysis of T3 and T4 with low specificity. The invention exhibits extremely high analytical sensitivity for all of the target analytes (femtogram level).

  • Patent number: 11058716
    Abstract: Provided are a method, target and application for NO accumulation to decrease invasiveness of Pseudomonas aeruginosa; achieving NO accumulation by means of external NO donors or disruption of internal NO metabolism in an environment where Pseudomonas aeruginosa is growing or being cultured, in order to decrease production by Pseudomonas aeruginosa of the invasion factor pyocyanin. Utilizing even micro-quantities of NO can significantly inhibit Pseudomonas aeruginosa PCN (PCN synthesis down 82% with 60 ?M SNP treatment); by inhibiting NO reductase, an enzyme related to NO metabolism, PCN synthesis can be significantly inhibited (the PAO1-?nor strain has 84% PCN reduction). Using NO donors or inhibiting enzymes involved in Pseudomonas aeruginosa NO metabolism as a means of combating bacterial infectious disease does not affect the body's normal microflora like traditional antibiotics.

  • Publication number: 20210147166
    Abstract: A print device comprising an input tray to receive a print media stack, and a load stop arm to manage print media feed, from the input tray, into a media loading path for printing. The load stop arm is to rotate between a media stacking state and a media feed state to manage the print media feed. The load stop arm comprising a trigger protrusion to move from a default position to a trigger position when the load stop arm rotates to the media stacking state in a low stack condition. The low stack condition indicates reduction of print media in the print media stack to an amount below a threshold value.
