Abstract: Provided are transaminase mutants and uses thereof. The transaminase mutant is obtained by one or more amino acid mutations occurring in SEQ ID NO: 2 or is a mutant with a conserved amino acid mutation obtained by taking the sequence SEQ ID NO: 1 of a wild-type CvTA transaminase as a reference. Compared with wild-type transaminases, the catalytic activity of the mutant is improved to different degrees, so that the production efficiency of chiral amine compound synthesis may be improved.

Abstract: An application interface layout method includes that a developer sets a layout container having an adaptive layout capability in a layout file of an application, where the adaptive layout capability includes at least one of an extension capability, a proportion capability, an equalization capability, a wrapping capability, a hiding capability, a stretching capability, or a scaling capability. In this way, when running the application, an electronic device arranges, based on a screen parameter of the electronic device and the adaptive layout capability of the layout container in the layout file, a size and a location of a child view in the layout container on a display interface.

Abstract: A method and apparatus for non-contact infrared measurement of surface temperature. A method includes providing an infrared temperature measurement system, and increasing an emissivity of an interface between a metal and an infrared transparent window across which shear stresses are transmitted.

Abstract: In one aspect the present invention concerns methods and apparatus for measuring the mechanical properties of soft materials across a frequency regime. In particular, the present invention concerns methods and apparatus using torsional waves to measure the mechanical properties of vocal fold tissue and candidate materials for use in human vocal fold reconstruction. In embodiments of the present invention, sample material is placed between two plates whose sides are faceted. One of the plates is attached to the shaft of a galvanometer, and the plate is twisted back and forth through angles of up to ±6° at frequencies of up to 2500 Hz. If required, the assembly may be enclosed in an environmental chamber to maintain the temperature and relative humidity of the sample at the conditions experienced by vocal folds in a living human or animal.
