Abstract: An opto chip for detecting a physical parameter of a liquid sample, comprising an optical structure monolithically integrated with a substrate layer and a functional layer, wherein the substrate layer is light-transmissive and configured to have an upper surface for receiving a droplet of the liquid sample and a lower surface bonded to the functional layer; and the functional layer comprises a light-emitting region and a light-detecting region with the light-emitting region being configured to emit measurement light. The light-detecting region is configured to receive reflected light derived from the measurement light and a signal reflecting the change in intensity thereof is converted into a photocurrent signal. A viscometer and detection method operated using the same opto chip technique. The need for complex external optical calibration is thus eliminated, making the viscometer easier to operate and reducing the overall size of the device.

Abstract: The present invention provides a scalable method for achieving shape control of diamond micro-nanoparticles, comprising air oxidizing diamond micro-nanoparticles grown by chemical vapor deposition and/or diamond micro-nanoparticles grown by high pressure and high temperature. The present invention achieves the controllable morphology transformation of diamond micro-nanoparticles via air oxidation treatment. It has been demonstrated that a series of unique shapes, including “flower” shaped, “hollow” structured, “pyramid” patterned on the surface, and “boomerang” shaped, can be achieved by altering the air oxidation parameters, i.e., temperature and duration. The scalable production of these differently shaped diamond micro-nanoparticles represents a significant scientific breakthrough together with a high commercial value. The ability to produce diamond particles with desired shapes simply and cost-effectively will remove many obstacles to using diamonds for practical applications in nanophotonics, quantum computing, quantum optics, etc.

Abstract: An image feature extraction method and apparatus are provided, along with a computer device and a readable storage medium. After obtaining the target convolutional kernel of the feature extraction convolutional neural network, this application will cut the input feature map obtained from the preprocessed image according to the preset image size into multiple abutting input feature submaps. Each input feature submap will be zero-padded to obtain the preprocessed feature submap. Then, for each preprocessed feature submap, the Karatsuba algorithm will be used to reduce the multiplier resource consumption during the convolution operation between the target convolutional kernel and the preprocessed feature submap, effectively suppressing the growth of adder resource consumption during the convolution operation, resulting in the output feature submap. Subsequently, multiple output feature submaps will be overlapped and the boundary of the overlapped feature map will be cropped to obtain the output feature map.
