It reviews discotic colloids sized from nanometers to micrometers with attention devoted to the synthetic colloidal disks, their assembly, and their roles in soft condensed matter and material science. Various strategies have been utilized to synthesize discotic colloids, including nanocrystal growth via selective surfactant adsorption, controlled precipitation, exfoliation of layered structure compounds, shape changing of liquidcrystal emulsions. These disks have been employed to study liquid crystalline phase formation and suspension rheology. Diskpolymer nanocomposites, such as Nylonclayhybrid (NCH) and αZrPepoxy, have wide applications in advanced functional material engineering. A special attention is drawn on the human red blood cells (RBC) for the research of its flow and deformation towards medical benefits.

As statistics characterizing the strength of statistical relationship between two random variables,correlation coefficients have found wide applications in nearly all science and technology  fields.This  paper attempts to provide a detailed review on 5 commonly used correlation coeffcients in the literature, including a relatively detailed discussion on their statistical properties under the fundamental bivariate normal model and their suitable application scenarios. Specifically,(1) if the sample follows normal distribution, then the  Pearsons Product Moment Correlation Coefficient is optimal;(2) if the monotone nonlinear distortion in the sample is small, then the Order Statistics Correlation Coefficient should be used;(3) if the monotone nonlinear distortion in the sample is severe, then the Spearmans rho or Kendalls tau are feasible;(4) if only one channel is distorted by monotone nonlinearity, then the Gini Correlation is best choice; and (5) if there exsits impulsive noise in the sample, then  the Spearmans rho or Kendalls tau should be employed.

Strategy generation is the key factor for scientific decisionmaking; extension strategy generation is an important method of settling conflicts in extension engineering. While analyzing the decision tree classification, it presents an acquisition method of extension strategy. It remines and transforms the decision tree rules from “can’t to can, not to yes” strategy, based on the extension set and extension transformation theory. The strategy applies simple and intuitive decisionmaking to the retention of the customer. Its application in a web company has proved that this method is highly feasible, and also has the reference value for the research on other methods based on extension.

The extension set is a new set approach to the resolution of the contradictory and noncompatible problems. It mainly investigates the matrix representation of the extension set operation. First, some operations such as set intersect ∩、set union ∪ and set complement C, based on the max and min of the absolute value, were introduced to extension sets，and their serial properties were also proved. Then, the matrix representation of extension transformations was defined on the finite extension set universe, and some properties of the composition extension relations, extension transformation and extension equivalence were discussed.

Many potential and valuable rules can be derived from data via clustering mining in an effective and accurate way, which can lead to security threats such as the disclosure of user privacy. Many privacypreserving researches on clustering mining have been conducted, especially on multiplicative perturbation (MP) that is a highly secure and accurate method. Research finds known knowledge independent component analysis (KKICA) can greatly reduce the privacy security of existing MP. It can approximately estimate private data from MP data. To solve the problem, partial rotation perturbation (PRP) is proposed. The analysis of accuracy shows that PRP has zeroloss accuracy. The analysis of security proves that PRP can defend attack from the KKICA availably and is more secure. PRP is applied in clustering mining. The results are very similar to unpreserved clustering mining results, which shows that MP is practicable. The existence of PRP solves the problem with the security vulnerability of existing MP effectively, making the application of clustering more secure.

It discusses the saddlepoint equilibrium strategy for indefinite affinequadratic stochastic differential games in continuous time. By introducing a generalized Riccati differential equation (GRDE), it proves that under the condition of Its differential rule, the solvability of GRDE is both the sufficient and necessary condition for the existence of equilibrium strategies. Meanwhile, the explicit solution of equilibrium strategies with closed forms and the optimal value of cost function are obtained. The results expand the previous results of the ordinary deterministic differential games and stochastic differential games with definite weight cost matrices.

In view of the limitations of arbitrary degree cutting, the deficiency of model inside interaction and the low precision of cutting of medical images, a new method of the second extraction of 3D virtual slices is proposed, based on interactive location. On the Visual C++ platform, with the highly flexible and portable VTK, this method was used to cut again the tooth model to compensate for the problem of weak interaction and low precision. The new method has good interaction and realtime. Meanwhile, this method can be used to cut again any arbitrary part of  the 3D model, so it has good application prospects in the medical field.

The bacterium growth curve was determined via the two methods, surviving bacteria count and spectrophotometry, used to study the growth characteristics of a bacterium called JS17. The results obtained by means of the surviving bacteria count can reflect the actual number of live bacteria，but this method needs many operations and it is timeconsuming. It is more convenient to use the spectrophotometry method, but the results got by means of this method were influenced by other suspended matter, which were possibly the chemical reaction materials or metabolism products of JS17. The growth curve of JS17, with shaking culture in 2# oil medium, shows that lag phase in 0~20 h，log phase in 20~48 h, stationary phase in 48~72 h and decline phase emerge after 72 h. The results suggest that the suspended matter affects the rule of growth curve. The metabolism of the suspended matter of bacterium JS17 deserves further study.

The tube method was used to study two different extenders to cryopreserve by vitrification the 2-cell Wistar Rat embryos, which were DAP213 and SDP0323. And the effects of different extenders on the average survival rates of frozenthawed embryos and on the average rates of the new borns were discussed. The average survival rates and average new born rates after being frozenthawed were 57.1%,69.1% and 34.9%,41.1% respectively. There are no significant differences between the two extenders using the Student' t-Test, but both the average survival rates and average new born rates with SDP0323 are higher than those with DAP213. The results show that the tube method with DAP213 and SDP0323 for cryopreservation of the 2-cell rat embryos has been successful, and that the two extenders are suitable for the rat 2-cell embryos-bank.

It establishes an improved fiber plate method, which can be used for qualitative and semiquantitative analysis. Several key factors were studied and discussed. The concentration of fibrinogen and plasminogen contained in the fibrin plate did not have any effect on the fibrinolytic area. However, the concentration of fibrinogen had influence on the observation and image gathering of fibrinolytic zones. It was difficult to clearly observe the fibrinolytic zones when the concentration of fibrinogen was below 02 mg/mL. The logarithm of the product of the two perpendicular diameters was linearly related to the logarithm of the concentration of urokinase when the concentration of urokinase was among 2~250 mU/μL. In the experiment, the optical concentration of urokinase was among 10~20 mU/μL. It is found that it is hard to denature plasmin by heating the agarfibrin plate after the agar is solidified. However, the plasmin is completely denatured when heated at 95 ℃ for 40 minutes before the agar is solidified.

The relationship equation has been obtained, which can be used for the design of similar heat transfer equipment.

The 5083H321 aluminum alloy plate was jointed by friction stir welding. The comparative studies of the organization of weld and base metal were conducted with optical microscopy, scanning electron microscopy, electron back scattered diffraction and orientation imaging microscopy.

The grains of the nugget zone show homogeneous and equiaxed morphology characteristics of dynamic recrystallization.
