Abstract: A fusion protein being a lipid-free reference standard having good long-term storability, which is used for measuring the quantity or quality of modified HDL, and a method for accurately, repeatability and reliably measuring high-density lipoprotein using the same. In the fusion protein, a complete protein sequence or partial fragment protein sequence for ApoA I is linked directly or via a spacer to a LOX-1 binding protein sequence that binds to a lectin-like oxidized LDL receptor: LOX-1. The method for measuring a modified high-density lipoprotein in a test sample is a method for measuring a modified high-density lipoprotein through binding of the modified high-density lipoprotein to LOX-1 and an anti-APOA I antibody, wherein, using the fusion protein as a reference standard for the modified high-density lipoprotein, the modified high-density lipoprotein in the test sample is determined by comparison with the reference standard through optical detection and/or radiation dosage detection.

Abstract: A computer-controlled load pull tuner is embedded in a quarter-circle waveguide-to-wafer-probe adapter and creates a compact and handy assembly. The tuner includes two, along the 90-degree arc of the waveguide, sliding carriages, each holding a tuning probe inserted at fixed penetration without cumbersome vertical axis mechanisms. The carriages holding the tuning probes are spring preloaded against the waveguide wall and can tilt, when hitting a stop, lifting the tuning probes out of the waveguide cavity, thus allowing for a low residual reflection and high transmission behavior. On top of full load pull capacity, the assembly can be used for instantaneous s-parameter measurement when the tuning probes are lifted. High-speed calibration and tuning algorithms allow efficient operation.

Abstract: Described herein are multiplexed impedance-based detection methods for identifying each type of impedance-encoded particles and systems for performing these methods. Impedance-encoded particles of each type comprise cores having the same structure and producing the same complex electrical impedance signature when an AC signal is applied to these particles. At the same time, different types of particles have different structures and produce different complex electrical impedance signatures, which allow differentiation of the different types of particles. In some examples, different types of particles have different functionalization, resulting in different analytes binding to or otherwise reacting with these particles. As such, these particles may be arranged into a test media to detect different analytes based on identifying each type of impedance-encoded particles using complex electrical impedance signatures.

Abstract: A highly secure file system stores and accesses files utilizing familiar hierarchical concepts for file storage (i.e. root directory, directory, file entry data, etc.), while at the same time hiding the actual path to access the desired file. A file may be stored and accessed at a data store node using a Uniform Resource Identifier (URI) path comprising a unique, unidirectional relationship identifier that controls a requesting entity's access to the file system. The URI path may also comprise a “leaf” unique uniform identifier (UUID) derived from linkages between the hierarchical nodes superordinate to the data store node.
