Disclosed is a nitrile derivative compound represented by formula (I), a stereoisomer, a deuterated product, a co-crystal, a solvate or a pharmaceutically acceptable salt thereof, wherein each group is as defined in the description. The compound has dipeptidyl peptidase 1 inhibitory activity and can be used to prepare a drug for treating diseases including obstructive airway diseases, bronchiectasis, cystic fibrosis, asthma, emphysema, and chronic obstructive pulmonary diseases.

Nitrile derivative that acts as inhibitor of dipeptidyl peptidase 1 and use thereof

The present invention provides a system for data mapping and storing in digital three-dimensional oscilloscope, wherein the fixed coefficients, which are calculated according the parameters and settings of a digital oscilloscope, are stored into a fixed coefficient memory CO RAM, the fixed coefficients are outputted to N fractional operation units through N−1 D flip-flop delay units to multiply with the acquired data x(n) and then be accumulated, thus N fractional calculus results are obtained. In this way, N fractional calculus results can be obtained by performing L/N fractional calculus operations. N fractional calculus results are sent to a signal processing and display module, in which they are converted into a display data through a drawing thread, and the display data are sent to LCD for displaying, thus the fractional calculus operation and display of a input signal in a digital oscilloscope is realized.

Digital oscilloscope having fractional calculus operation and display function

Provided is a system for communication. The system includes: a basic function module; at least one extended function module; a first near-field communication transceiving unit and a first near-field communication antenna unit, located on the basic function module; and at least one second near-field communication transceiving unit and at least one second near-field communication antenna unit, located on each of the at least one extended function module. The first near-field communication antenna unit and the at least one second near-field communication antenna unit respectively comprise a first loop antenna and a second loop antenna which are printed on a printed circuit board.

System and modules for communication

A system maps and stores data in digital three-dimensional oscilloscope, wherein an ADC module has four ADC submodules. Four acquired waveform data are sent to an extraction module, and buffered in a FIFO module. When a trigger signal arrives, FIFO module outputs four extracted waveform data to a mapping address calculation module for calculating a mapping address and a RAM serial number for each point data, and the waveform data comparison and control module performs the reading and writing control of the 4&#xd7;N dual port RAMs. When mapping number reaches a frame number, the RAM array module outputs its waveform probability values to the upper computer module to convert each value into RBG values, and the display module displays the waveforms of input signals of four channels on a screen according the RBG values.

System for data mapping and storing in digital three-dimensional oscilloscope
