Abstract: A nucleic acid aptamer specifically recognizing soluble ST2 protein and its application, belonging to the field of variation or genetic engineering, are described. The technical problem addressed includes how to specifically detect sST2 protein. In order to address this technical problem, nucleic acid aptamers of single-stranded DNA with nucleotide sequences are shown in SEQ ID No. 1-10, respectively. SELEX technology, combined with high-throughput sequencing technology and bioinformatics analysis, reduces the rounds of screening and obtains candidate nucleic acid aptamers, and further analyzes its affinity and specificity to obtain a nucleic acid aptamer that specifically recognizes sST2 protein. The nucleic acid aptamer has the characteristics of high specificity, high stability, convenient synthesis, and easy labeling of functional groups, and the like, and may be used for the detection of sST2 protein and the preparation of biosensors, diagnosis and prognosis of cardiovascular diseases and other products.

Abstract: Techniques for enhancing the absorption of photons in semiconductors with the use of microstructures are described. The microstructures, such as pillars and/or holes, effectively increase the effective absorption length resulting in a greater absorption of the photons. Using microstructures for absorption enhancement for silicon photodiodes and silicon avalanche photodiodes can result in bandwidths in excess of 10 Gb/s at photons with wavelengths of 850 nm, and with quantum efficiencies of approximately 90% or more.

Abstract: An approach is provided for securing a secret for usage by an application utilizing a client to retrieve secrets. A request is sent from a client in a workload container within a trusted execution environment (TEE) to retrieve an encrypted secret from an application programming interface (API) server outside the TEE. The request is hooked and sent to the API server by a proxy or a secret proxy plugin within the TEE. The secret is received from the API server by the proxy or secret proxy plugin. An agent within the TEE is called to request a private key. The agent obtains the private key. The secret is decrypted by using the private key. The decrypted secret is returned to the client by the proxy or secret proxy plugin, which ensures that a plain text version of sensitive information in the decrypted secret is not accessible outside the TEE.

Abstract: Methods, devices and media for two-pass source code transformation from a first high-level programming language to a second high-level programming language are described. Two different source code transformation technologies are combined to produce a two-pass source code transformation method: a compiler-based source code transformation technique is used in a first pass, and a parse-tree-based source code transformation technique is used in second pass. The second pass may be used to automatically refactor the source code to enhance desired properties of the second programming language. A two-pass C-to-Rust transformation technique, CRustS, is described which automatically generates Rust source code that exhibits memory safety and overcomes other limitations of existing tools such as C2Rust.

Abstract: A mesh woven structure with capillary action is applied to a two-phase fluid heat dissipation unit. The mesh woven structure includes multiple latitudinal lines and multiple longitudinal lines. At least two longitudinal lines are selectively arranged as a longitudinal line set. The mesh woven structure is woven from the single latitudinal line and one cooperative longitudinal line set, which sequentially repeatedly intersect (and overlap with) each other. Accordingly, the number of the voids of the mesh woven structure is increased so that the mesh woven structure has better capillary attraction and water collection (containing) ability to greatly enhance the heat transfer performance.

Abstract: A woven mesh structure with capillary action is applied to a two-phase fluid heat dissipation unit. The woven mesh structure includes multiple longitudinal lines and multiple latitudinal lines. At least two latitudinal lines with same thickness are selectively arranged as a latitudinal line set. The woven mesh structure is woven from the single longitudinal line and one latitudinal line set, which sequentially repeatedly intersect (and overlap with) each other. Accordingly, the number of the voids of the woven mesh structure is increased so that the woven mesh structure has better capillary attraction and water collection (containing) ability to greatly enhance the heat transfer performance.

Abstract: The present invention describes a test kit for the detection of fat-soluble vitamins in serum using a method based on high performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS). The internal standard (IS) solution included in the kit is based on methanol, acetonitrile and isopropyl alcohol solvents. Ammonium acetate is added to the IS solution to make it more stable and last for longer storage time. The application of this kit can significantly improve the recovery and detection sensitivity of vitamins A, E, K1 and K2 in serum without additional sample enrichment, make sample preparation process simpler and more efficient, keep processed samples stable for longer time, and lower the overall cost for more accurate and repeatable test results.
