Many industrial processes such as heating furnaces have over damping dynamic characteristics. Based on an innovative impulse response model, a method of identification and control for the over damping plant is introduced in the paper. The number of parameters of the model is much less than conventional impulse response model. The model based on tuning procedure of numerical optimum PID controller parameters is presented. For an actual instance, a large scale airflow circulatory resistance furnace control system with cascades of time delays is developed. In the system, the optimum PID control is used in the inner loop. A nonlinear PI compensation control is applied in the outer loop. The coordinating control among each output is realized by a fuzzy control strategy. A process surveillance organization monitors running situation of system and tunes controller parameters.

The development of new drugs is traditionally focused on a single target protein. Only recently has it been recognized that drugs, i.e., small molecules, usually bind to several target proteins and thus have a wider spectrum of different effects (Konc, 2019). Natural substances are very interesting in this respect, as more than 32% of all drugs on the market today are derived from natural sources. However, natural substances are largely unexplored as their exact mechanisms of action are often unknown (Baran, 2018). In order to determine their actions, we can resort to computational methods. Computational screening enables the identification of potential target proteins, the explanation of observed effects and the prediction of novel effects of natural compounds. Computer algorithms enable targeted investigations, such as focused experimental tests on a specific target protein or a family of potential target proteins.

The formation of neural circuits is governed by multiple classes of highly conserved extracellular guidance signals such as guidance cues,growth factors,and cell adhesion molecules(Kolodkin and Tessier-Lavigne,2011;Stoeckli et al.,2018).During embryonic development,vertebrate commissural neurons project axons toward the floor plate and cross the midline of the spinal cord,a process relying upon the coordination of attractive and repulsive guidance cues(Kolodkin and Tessier-Lavigne,2011;Stoeckli et al.,2018).

Public health is the science and art of preventing disease, prolonging life and prompting physical and mental health through evaluation, policy development and sanitary measures. The development of public health has become an important part of health care reform in China, and it requires the participation of Chinese medicine(CM) in the practice of public health. This study analyzed the problems of CM services in public health, suggested that the identification of CM constitution could propose an application paradigm of CM services in public health, and described from aspects of theory, technology and application. The identification of CM constitution gained national approval and support of government and industry. With the application and popularization of this technology, it will promote the establishment of characteristic CM preventive care system and the development of public health.

The sweet potato whitefly, Bemisia tabaci, is a complex species, and many of its biotypes are important agricultural pests. The B and Q biotypes are invasive and coexist with the native Cv biotype on vegetable and ornamental crops in China. In this study, these three bio- types were identified based on their morphological characteristics, RAPD-PCR analysis, and DNA sequences of the COI gene. The ante-rior and posterior wax fringes of the B, Q, and Cv biotypes significantly differed from each other. Based on this morphological characteristic, the three biotypes can easily be distinguished in greenhouses and fields. Genomic DNA RAPD-PCR band patterns also revealed differences between these biotypes using the H16 primer. The B biotype has three bright DNA bands between 250 and 600 bp, the Q biotype only has one bright band at 300 bp, while the Cv biotype has no band between 250 and 500 bp. Both the Cv and Q biotypes have two bright bands at 750 and 1000 bp while the B biotype has only one band at 1000 bp. Based on the COI gene, the genetic identity between B and Cv, B and Q, and Q and CV was 85.8%, 94.7%, and 86.0%, respectively. The MP tree indicated that the phylogenetic relationship between the B and Q biotypes is much closer than that between the B and Cv or the Q and Cv biotypes. The uses of the morphological, RAPD-PCR, and DNA sequencing methods in biotype identification of B. tabaci are discussed.
