According to the characteristics of periodicity and randomness of traffic flow, a nonlinear forecasting model of time series is put forward. Firstly, the data of time series for one-dimensional traffic flow is converted to multi-dimensional time series and then the RBF neural network with strong nonlinear prediction ability is used for modeling. Finally, the model is tested by simulation experiments. The simulation results show that the prediction accuracy of forecasting model of time series for traffic flow with the RBF neural network being adopted is higher than that of the traditional model and the results can be applied to traffic management. © 2017, UK Simulation Society.

Unripe apples contain significant amount of phenolics with various health benefits. A pilot scale enrichment process of unripe apple phenolics with Viscozyme L extraction and XAD-7 sorption process, based on the total phenolic content (TPC), phenolics content by high-performance liquid chromatography analyses, and antioxidant activities were studied. Antioxidant activities were tested by measuring oxygen radical absorbing capacity (ORAC), 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, and ferric-reducing antioxidant power (FRAP). The phenolics-rich final product, apple antioxidant phenolics (AAP) has 771-fold higher TPC and 600-fold higher antioxidant activity of unripe apples. Through XAD-7 sorption AAP showed 52, 87, 70 and 44-fold increases in TPC, ORAC, DPPH and FRAP values, respectively. AAP showed more than 95% stability at the temperature range of 20 to 120°… and pH range of 1.47 to 8.5. Apple phenolics extraction process of Viscozyme L extraction coupled with XAD-7 sorption could be applied to the production of health benefit antioxidants. © 2014, The Korean Society for Applied Biological Chemistry.

The hydraulic control system, an important composition of parallel machine tool, is a high order, nonlinear, parameter uncertain system, which seriously affects the dynamic performance of a machine tool, so it is very difficult to gain good performance with traditional control methods. The sliding mode control method based on RBF neural network is proposed in this paper. From the simulation results we can obtain that the proposed method is better than the traditional sliding model control method. Moreover, the result validates the proposed method of Hydraulic system for parallel machine tool and also provides the theoretical and experimental basis. © Yang et al.

Cytotoxic T lymphocyte associated antigen-4(CTLA-4) is an inhibitory receptor with great value in the progression of hepatitis C virus (HCV) infection related diseases. To determine the potential associations of IL-28B rs12979860 and CTLA-4 rs231775, rs3087243 and rs5742909 polymorphisms with the generation of HCV F protein, susceptibility and outcomes of HCV infection, a total of 375 healthy controls, 219 HCV spontaneous recovered patients and 600 chronic HCV patients from Southeast China were recruited and genotyped in this study. And the relative mRNA levels of CTLA-4 in T cells were detected. Logistic regression analysis showed that rs231775 A allele was associated with significantly higher rate of spontaneous viral clearance in anti-HCV F antibody negative patients (adjusted OR=0.512, P=0.008), but allele A was related to higher mRNA level of CTLA-4 with the generation of HCV F protein. And rs5742909 T allele added up to the risk of HCV infection chronicity significantly in patients with the presence of HCV F protein (adjusted OR=2.698, P=0.003). Also, the rs5742909 CC genotype, along with the presence of HCV F protein, indicated a significantly higher CTLA-4 level than that in anti-HCV F antibody negative patients. The AG+AA genotype of rs3087243 significantly increased the susceptibility to HCV infection in subjects over 56 years old (adjusted OR=1.595, P=0.011). Genotype-genotype interaction between IL-28B rs12979860 and CTLA-4 rs3087243 was found to be significantly associated with increased susceptibility to HCV infection (adjusted OR=1.509, P=0.005). Haplotype analysis in CTLA-4 also showed significant association with the generation of HCV F protein. All these results indicated the importance of IL-28B and CTLA-4 polymorphisms and their associations with HCV F protein in the risk and chronicity of HCV infection in Chinese Han population in Southeast China.

A simple HPLC method to determine the amount of 10-methoxycamptothecin (MCPT) and its major metabolite 10-hydroxycamptothecin (HCPT) in rat liver tissue was developed in the present study. Camptothecin (CPT) was used as internal standard (IS). A piecewise linear function was used over lower and higher concentrations, respectively. The calibration curves were linear (r (2) >0.99) over concentrations from 2.5 to 20 ng/mL and 20 to 320 ng/mL for both MCPT and HCPT. The method had an accuracy of 92.74% to 112.76%, and the intra- and inter-day precision (RSD%) were 11.85% or less for MCPT and HCPT. The stability data showed no significant degradation occurred under the experimental conditions. This method was successfully applied to the tissue distribution study of MCPT and its metabolite HCPT in liver tissue samples after intravenous administration. © Georg Thieme Verlag KG Stuttgart · New York.

Bioisosteres are a class of compounds or groups,these compounds with similar molecular shapes or volume, similar electronic distribution, and similar physical properties. Bioisosteres play a role in the same related biochemical system as agonist or antagonist, which possessed in related biological activities. The amide structure can be an important part of drugs and a constituent of a pharmacophore. However, the presence of this moiety can also be responsible for some significant drawbacks about drug molecular, including metabolic instability, toxicity, as well as limited passive diffusion across biological membranes. To avoid some of these shortcomings while retaining the desired attributes of the amide moiety, bioisosteric replacement of the amide moiety in lead compounds is an effective method. Through the amide bioisosteric replacements, other aims would be goal such as increasing the target potency and selectivity, developing new structures to expand or break through the patents and decreasing the difficulty of the synthesis of the compounds. This review focuses on the application of the replacement between amide and amide bioisosteres in the optimization of lead compounds in recent five years. We wish our review would offer a new thinking in the design and optimization of the compounds in the research and development of the new drugs. © 2016, Editorial Office of Progress in Chemistry.

In order to improve the automation of end-hole drilling process in the production of suture needles with thread, a high-precision subpixel-based drilling method is proposed. According to the edge detection principle in mathematical morphology, combined with the characteristics of the magnified images of the ends of suture needles to be drilled, the morphological edge detection operators with variable structural elements are constructed to achieve noise suppression and fully extract the detailed information of edges of images of needle end holes to be drilled. Then, the subdivision method of spatial moments is adopted to realize the subpixel positioning of pixel-level edges. Finally, least squares fitting method is used to achieve the high-precision positioning of center of needle end hole to be drilled. The experimental results of the 0.5 mm needle samples show that, the drilling method proposed in this study has a concentricity error no more than ± 0.2 μm and an average drilling time of 0.65S, boasting good real-time performance and stability and meeting the automated production needs of drilling process of suture needles with thread. © 2014, Sun and Li; Licensee Bentham Open.
