The Okinawa Trench in the East China Sea and the Manila Trench in the South China Sea are considered to be the regions with high risk of potential tsunamis induced by submarine earthquakes. Tsunami waves will impact the southeast coast of China if tsunamis occur in these areas. In this paper, the horizontal two-dimensional Boussinesq model is used to simulate tsunami generation, propagation, and runnp in a domain with complex geometrical boundaries. The temporary varying bottom boundary condition is adopted to describe the initial tsunami waves motivated by the submarine faults. The Indian Ocean tsunami is simulated by the numerical model as a validation case. The time series of water elevation and runup on the beach are compared with the measured data from field survey. The agreements indicate that the Boussinesq model can be used to simulate tsunamis and predict the waveform and runup. Then, the hypothetical tsunamis in the Okinawa Trench and the Manila Trench are simulated by the numerical model. The arrival time and maximum wave height near coastal cities are predicted by the model. It turns out that the leading depression N-wave occurs when the tsunami propagates in the continental shelf from the Okinawa Trench. The scenarios of the tsunami in the Manila Trench demonstrate significant effects on the coastal area around the South China Sea.

This investigation was aimed at evaluating the effectiveness of corrosion inhibitors in increasing the chloride threshold value for steel corrosion. Three types of corrosion inhibitors, calcium nitrite （Ca（NO2）2）, zinc oxide （ZnO）, and N,N＇-dimethylaminoethanol （DMEA）, which respectively represented the anodic inhibitor, cathodic inhibitor, and mixed inhibitor, were chosen. The experiment was carried out in a saturated calcium hydroxide （Ca（OH）2） solution to simulate the electrolytic environment of concrete. The inhibitors were initially mixed at different levels, and then chloride ions were gradually added into the solution in several steps. The open-circuit potential （Ecorr） and corrosion current density （lcorr） determined by electrochemical impedance spectra （EIS） were used to identify the initiation of active corrosion, thereby determining the chloride threshold value. It was found that although all the inhibitors were effective in decreasing the corrosion rate of steel reinforcement, they had a marginal effect on increasing the chloride threshold value.

Nine piggyBac-like elements （PLEs） were identified from the cotton aphid Aphis gossypii Glover. All the PLEs shared high sequence similarity with each other. However, eight of the nine PLEs were unlikely to encode functional transposase due to the existence of disruptive mutations within the coding regions. The other one PLE contained major characteristics of members in the piggyBac family, including TTAA target site duplications, inverted terminal repeats （ITRs）, and an open reading frame （ORF） coding for a transposase with a putative DDD domain. This one with an intact transposase ORF was named AgoPLE1.1. The predicted transposase shared 47% similarity with that of Trichoplusia ni piggyBac IFP2. Phylogenetic analyses showed that AgoPLE1.1 was most related to the Heliothis virescens PLE1.1 （HvPLE1.1） element, with 45% and 60% similarity at the nucleotide and amino acid levels, respectively. A functional assay demonstrated that AgoPLE1.1 encoded a functional transposase and was able to cause precise excision in cell cultures. On the other hand, few genomic insertion polymorphisms of AgoPLEI were observed in the genome of the cotton aphid. These observations suggested that AgoPLE1.1 was a PLE that invaded the cotton aphid genome in recent periods and retained its activity.

Proteomic analysis was applied to generating the map of Arabidopsis mature pollen proteins and analyzing the differentially expressed proteins that are potentially involved in the regulation of Arabidopsis pollen germination. By applying 2-D electrophoresis and silver staining, we resolved 499 and 494 protein spots from protein samples extracted from pollen grains and pollen tubes, respectively. Using the matrix-assisted laser desorption ionization time-of-flight mass spectrometry method, we identified 189 distinct proteins from 213 protein spots expressed in mature pollen or pollen tubes, and 75 new identified proteins that had not been reported before in research into the Arabidopsis pollen proteome. Comparative analysis revealed that 40 protein spots exhibit reproducible significant changes between mature pollen and pollen tubes. And 21 proteins from 17 downregulated and six upregulated protein spots were identified. Functional category analysis indicated that these differentially expressed proteins mainly involved in signaling, cellular structure, transport, defense/stress responses, transcription, metabolism, and energy production. The patterns of changes at protein level suggested the important roles for energy metabolism-related proteins in pollen tube growth, accompanied by the activation of the stress response pathway and modifications to the cell wall.

Metabolic(dysfunction)associated fatty liver disease:more evidence and a bright future

第43届中国控制会议

作者： Ruru jia Yuan-hua Ni Guangchen wang College of Artificial Intelligence Nankai University

This paper discusses the distributed event-triggered time-varying formation(TVF) problem for high-order multiagent systems(MASs) with multiplicative noise on the undirected graph. Based on relative state measurements among agents, a distributed TVF protocol with multiplicative noise for MASs is proposed via event-triggered control. Then, a specific algorithm design is given and corresponding sufficient conditions are established, which shows that all agents can asymptotically converge to the target formation in the mean square sense. Finally, a numerical example is presented to prove the availability of the designed algorithm.
