Abstract: The invention relates to a wide spectrum multi-band detection structure with selective absorption enhancement and its preparation method. The structure comprises a plurality of sub-pixel units capable of detecting incident light in different bands. Each sub-pixel unit is composed of a square well-shaped microstructure array and a metal lower electrode (2), a photosensitive layer (3) and an upper electrode (4) on the surface thereof. The size and array spacing of square well-shaped microstructures in different sub-pixel units are determined according to the detection bands of the sub-pixel units where they are located. The upper openings of the square well-shaped microstructures are hollow to form a resonant cavity, and the adjacent square well-shaped microstructures in the same sub-pixel unit form a resonant cavity, thus solving the problem that the detector structure in the prior art cannot simultaneously realize visible light-near infrared multi-band absorption enhancement detection.

Abstract: Disclosed is a system and a method for information distribution. The system comprises: a server for generating a group key and its corresponding key deriving parameter, wherein the server encrypts sensitive contents by using the group key to obtain encrypted information; and terminals configured to receive the encrypted information through an open channel, extract the group key, then decrypt the encrypted information by using the group key to obtain the original content. In the group forming process, each terminal encrypts its private identifier using the public key and submits the ciphertext to the server. In information distribution process, the server transmits the ciphertext of sensitive contents and the key deriving parameter to the terminals via open channel Because private information available only to respective group members is required for calculating the group key, this mechanism ensures that the sensitive content can be transmitted securely on the open channel.

Abstract: New benzodiazepine compounds, and a preparation method therefor and the use thereof are provided. Short-acting benzodiazepine derivatives have the characteristics of a fast onset, short acting time, deep strength, being quickly metabolized, fast wake-up, etc. In anesthesia experiments on mice and rats, short-acting benzodiazepine derivatives have a comparable onset time to remazolam, but have a significantly shortened acting time and wake-up time. Moreover, some of the compounds have a significantly enhanced depth of action. Thus, the compounds have the characteristics of a faster onset, shorter acting time, greater strength of action, being metabolized faster, faster wake-up, etc. In long-term infusion anesthesia experiments on rats, compared with remazolam, the short-acting benzodiazepine derivatives have a significantly shortened wake-up time and recovery time, and have the characteristics of faster wake-up, a faster recovery, etc.

Abstract: In a method of forming a photonic device, a first silicon electrode is formed, and then a germanium active layer is formed on the first silicon electrode while including n-type dopant atoms in the germanium layer, during formation of the layer, to produce a background electrical dopant concentration that is greater than an intrinsic dopant concentration of germanium. A second silicon electrode is then formed on a surface of the germanium active layer. The formed germanium active layer is doped with additional dopant for supporting an electrically-pumped guided mode as a laser gain medium with an electrically-activated n-type electrical dopant concentration that is greater than the background dopant concentration to overcome electrical losses of the photonic device.

Abstract: A system and method provides seamless switchover of a user device (UE) between a mobile data network and a wireless network while providing policy and charging control (PCC) of the data session in the mobile data network. A mobile core network component is made ASF aware to process user data traffic related to an auto switching function (ASF) server from a UE client located on the UE using a special access point name (APN). The mobile core network component then uses a dedicated deep packet inspection (ASF DPI) for all data transfers to the special APN. The core network component is then able to process the UE data traffic seamlessly as the traffic is toggled between the ASF tunnel the WiFi tunnel. By monitoring the data traffic on the ASF tunnel, the core component (GGSN/PGW) is able to provide PCC for the data session.

Abstract: A chip-scale, air-clad semiconductor pedestal waveguide can be used as a mid-infrared (mid-IR) sensor capable of in situ monitoring of organic solvents and other analytes. The sensor uses evanescent coupling from a silicon or germanium waveguide, which is highly transparent in the mid-IR portion of the electromagnetic spectrum, to probe the absorption spectrum of fluid surrounding the waveguide. Launching a mid-IR beam into the waveguide exposed to a particular analyte causes attenuation of the evanescent wave's spectral components due to absorption by carbon, oxygen, hydrogen, and/or nitrogen bonds in the surrounding fluid. Detecting these changes at the waveguide's output provides an indication of the type and concentration of one or more compounds in the surrounding fluid. If desired, the sensor may be integrated onto a silicon substrate with a mid-IR light source and a mid-IR detector to form a chip-based spectrometer.

The sensor uses evanescent coupling from a silicon or germanium waveguide, which is highly transparent in the mid-IR portion of the electromagnetic spectrum (e.g., between ?=1.3 ?m and ?=6.5 ?m for silicon and ?=1.3 ?m and ?=12.0 ?m for germanium), to probe the absorption spectrum of the fluid surrounding the waveguide.
