Abstract:
According to the data of testing moisture content, as well as the processing data of sample quality change of two types of shredded tobacco's and six different varieties of filter rods',the effects of cigarette shredded tobacco moisture content by filter rod were analyzed.It turned out that the moisture absorption and initial moisture content of filter rods could affect the equilibrium relationship between the filter rod and shredded tobacco moisture content and further changes in moisture content during storage period.If the initial moisture content of filter rods was lower than the equilibrium moisture content,it showed the performance of moisture absorption and the moisture content of finished cigarette dropped; Conversely,it showed the performance of moisture desorption,and the moisture content of finished cigarette rose.The activated carbon-biological filter rod and ternary double-grooved cavity nanoparticles composite filter rods had strong moisture absorption, it would absorb moisture from the shredded tobacco, resulting in significant reduction in the moisture content of cigarette, a decrease respectively 0.234% and 0.634%.

Abstract:
In order to solve the problem of time consuming and error pronein selecting optimal "brick" to assemble functional protein expression vector,based on statistical language model (SLM), a dynamic programming algorithm of protein expression vector was carried out. By collecting the statistical parameters of BioBrick standard parts and transforming the assembling process into SLM, a dynamic programming algorithm could be performed to choose suitable parts to compose the final genetic construction. The result showed this method had high accuracy,redundant operations could be reduced and the time and cost required for conducting biological experiment could be minimized. The method could be not only used to optimize a design in a synthetic biological robotic platform, but also independently used to automate the DNA assembly process in synthetic biology. It could also be iterated and then give out different optimized results for consideration.

Abstract:
In order to deal with the problem that the prediction accuracy of subcellular localization of apoptosis proteins is not high, a method of predicting subcellular localization of apoptosis protein based on ensemble learning and Gene Ontology (GO) annotation database was proposed. This method utilized the GO features of apoptosis proteins and their homologous proteins combined with the two layer integration strategy to predict subcellular localization of apoptosis proteins. In the first layer, several sets of feature vectors were formulated by the different number of homologous proteins, then it selected the distance weighted K-nearest neighbor classifier as individual classifier, trained sub-prediction models, and integrated these models by majority voting. In the second layer, the prediction model of the first layer was used as the sub-prediction model, and it integrated the different nearest neighbors' sub-prediction models by the majority voting. The results of Jackknife test showed that prediction accuracy of the method reaches 96.2% on the CL317 apoptosis proteins dataset, which was superior to other methods. In addition,this method could reduce the impact of the data imbalance.
