A wine decanter includes a housing and a variation magnetic field generator, where the variation magnetic field generator is configured to generate a variation magnetic field, and the variation magnetic field generator generates the variation magnetic field, so that a movement component that can sense a magnetic field moves in wine to make the wine move, thereby increasing contact between the wine and air. The decanting device includes a wine container, a movement component, and the decanter according to any one of the foregoing, where the movement component is placed inside the wine container, the decanter is connected to the movement component by using a magnetic field, and the decanter generates a variation magnetic field to drive the movement component to perform decanting. The structure of the decanter is simplified, thereby facilitating miniaturization, and making it convenient to carry the decanter, and also reducing noises.
摘要:
Assays can be used to detect mutations found in neoplasms of the pancreas, as well as for other neoplasms and other uses. Nucleic acids can be captured from body fluids such as cyst fluids. Thousands of oligonucleotides can be synthesized in parallel, amplified and ligated together. The ligated products can be further amplified. The amplified, ligated products are used to capture complementary DNA sequences, which can be analyzed, for example by massively parallel sequencing.

Light to current converter devices, such as solar cells, are disclosed. The devices may include via holes extending through the cell substrate and may include through-hole electrodes within the via holes. The through-hole electrodes may be made from one or more materials and may be hollow, partially hollow, or fully filled. Front and rear electrodes may also be formed on the device and can be made of the same or different materials as the through-hole electrode. The devices may include emitters located only on the top surface of the cell, located on the top surface and symmetrically or asymmetrically along a portion of the inner surface of the via holes, or located on the top surface and full inner surface of the via holes. Processes for making light to current converter devices are also disclosed.

摘要:
The present invention provides an optical communication method, comprising: performing modulation on the obtained bit stream data to generate modulated signals; performing differential encoding on the modulated signals to generate differentially encoded signals; converting the differentially encoded signals into electrical signals; and mapping the electrical signals onto optical carriers to generate optical signals for transmission. With the present invention, it is possible to enhance the system's capability of resisting inter-carrier interference without decreasing spectrum efficiency, hence improving the tolerance of existing optical communication systems towards laser linewidth, fast-changing PMD, optical fiber nonlinearity, inter-channel interference and other damages, greatly enhancing system performances.
