Abstract: An all-optical ultrasonic detection device based on light-induced ultrasound and laser interference. In the device, a first laser is connected to an optical switch, the optical switch is connected to a dielectric film and a second laser generates a reference laser beam and a plurality of detection laser beams. The reference laser beam generates a first frequency-shifted reference laser beam and a plurality of second frequency-shifted reference laser beams. The first frequency-shifted reference laser beam generates a carrier signal. The detection laser beams are reflected by the dielectric film and then interfere with the second frequency-shifted reference laser beams. The interference light passes through a fourth fiber coupler and reaches a second photodiode to generate a frequency-modulated signal. The frequency-modulated signal and the carrier signal are input to a frequency mixer to generate a mixed signal. An acquisition unit is configured to obtain a vibration signal for the to-be-detected object.

Abstract: A method for creating an underwriting decision tree includes: acquiring a sample training set including different sample attributes; calculating an entropy value gain that represents an effect of an attribute on an underwriting result of each attribute, according to the underwriting result of a sample of each attribute in the sample training set; taking the attribute with a highest entropy value gain as a current node of the underwriting decision tree, and dividing a sub-attribute corresponding to the attribute with the highest entropy value gain as a next node of the current node; extracting a divided sample training subset of the sub-attribute from the sample training set; determining the sample training subset as the sample training set, and calculating the entropy value gain of the sub-attribute recursively and dividing the sub-attribute till the divided sub-attribute of the next node satisfies a preset condition of becoming a leaf node of the underwriting decision tree.

Abstract: A method of querying a status of an electronic insurance policy includes: receiving an inputted policy number; querying an initial status and an operation flow set of the electronic insurance policy corresponding to the policy number when the policy number is a valid policy number; obtaining a mapped status subset according to a status total set to which the initial status belongs and a status that each operation flow in the operation flow set is mapped in the status total set; and displaying the initial status of the electronic insurance policy and the obtained status subset.

Abstract: Disclosed is a method for cancelling an insurance policy that includes: detecting whether a preset cancellation condition of an insurance policy is satisfied when the insurance policy is under an insurance-applying status or under a to-be-underwritten status; acquiring a corresponding cancellation period of the insurance policy if the preset cancellation condition of the insurance policy is satisfied; detecting within the cancellation period whether a first change instruction is received which first change instruction is intended to change the status of the insurance policy so that the preset cancellation condition of the insurance policy is no longer satisfied; and cancelling the insurance policy when the first change instruction is not detected. Further disclosed are a device for cancelling an insurance policy, an insurance system, and a computer-readable storage media.

Abstract: The present application discloses a method for allocating processing task of insurance service, a computer readable storage medium, a terminal device and an apparatus. This method comprises: determining a processing task to be allocated and an insurance service corresponding to the processing task; acquiring an evaluation factor of the insurance service; determining a processing authority level required by the processing task according to the acquired evaluation factor; determining institution authority levels of various insurance institutions according to the acquired evaluation factor and preset institution factors of the various insurance institutions; determining a first insurance institution entitled to handle the processing task according to the processing authority level and the institution authority levels; and allocating the processing task to the first insurance institution according to a preset allocation rule.

Abstract: A recombinant genetic construct is provided that includes at least two expression cassettes. Each cassette encodes for a chain or subunit of a target protein. The genetic construct preferably targets any expressed protein to the secretory pathway of the host cell. An application of present invention is found in expressing the two chains of human insulin through two separate expression cassettes on the same methylotrophic yeast expression vector. Mature, bioactive human insulin molecules are secreted through this method without resorting to any post-translational cleavage process.
