Abstract: A semiconductor device having cells is provided, with each cell including a gate. The device includes a gate pad, a gate busbar and gate lines. The busbar connects the gate pad to the gate lines, the gate lines connect the gate busbar to the gates of the cells, and each of the gate lines is disposed along a first axis. The gate busbar includes first portions each disposed along a second axis, and the second axis intersects with the first axis. The first portions are spaced apart from each other to divide the semiconductor device into emitter segments. Lengths of the emitter segments along the first axis changes with distances of the segments from the gate pad, so that gate signals arriving at the gates of the cells from the gate pad via the gate busbar and the gate lines are substantially consistent.

Abstract: A road structure reconstructed from large-scale independent underground garage and a construction method, which solves the problem of a newly constructed urban expressway passing through large underground space. The technical point is a construction method for the road structure reconstructed from large-scale independent underground garage, including the following steps: S100: segmentation for the garage, S200: preparation before construction: the materials and equipment required for construction are transported to the site, and the construction site is cleaned, S300: reconstruction for the front section, S400: reconstruction for the middle section, S500: reconstruction for the rear section. The inventiveness of the present disclosure is the application of segmentation construction, the front section is completely obsoleted, a transition section is provided at the middle, and the design of the rear section adopts a double-deck road, thus the original underground garage structure is fully utilized.

Abstract: Systems and methods are provided for excitation spectral microscopy using frame-synchronized acousto-optic scanning of fluorescent excitation wavelengths. Linear unmixing of the images of targets of components that are individually labeled with different fluorophores can be simultaneously imaged with high temporal resolution and low crosstalk and the local abundance of each fluorophore at each pixel can be quantified. Fluorophore decomposed micrographs of the sample can be obtained by rendering the abundance in each pixel as an image.
