Strategic Study of CAE 2010, Volume 12, Issue 3, Pages 4-14
To make a study on the anti-sliding stablity of foundation of hydraulic structures on subbed soils, and based on the result by anti-sliding tests of dragged concreting clip plates in foundation pits, the anti-sliding stablity of foundation on subbed soils was determind. There are 3 different forms of largest displacement with 8 different forms of silding move of subbed soils caused by the different maximum compressive stresses of eccentric loads on them. It is worked out a design method to determine the sliding frictional resistances and the forms of sliding moves of foundation subbed soils; a formula for the integal frication resistance to sliding for the structure;a formula for the the anti-sliding move of subbed soils and a rule to distinguish the plane sliding move of foundation subsoils with others. To analyze 3 structures which have been established provides a confirmation with the reality for the design method.

Strategic Study of CAE 2007, Volume 9, Issue 12, Pages 81-85
A novel endtoend data transmission scheme based on OFDM mechanism with good robustness against the RPE-LTP vocoder in GSM voice channel is proposed. According to the character of RPE-LTP vocoder, data are modulated to orthogonal lowfrequency sinusoidal carrier. In OFDM, the modulation is done by IFFT and the modulated signals are conformed to the time and frequency characters of RPELTP vocoder. The results of simulation show that the transmission bit rate of the proposed scheme reaches 2.4 kb/s,and the bit error rate of the scheme is lower than 0.3 %. This scheme provides a new approach for realtime secure voice data transmission over GSM system.

A typical cavitation erosion resisting sample,the weld deposited coationg of boronic stainless steel, and a typical erosion and abrasion resisting sample,the weld deposited coating of WC ceramic are micro-analyzed and studied by means of light microscope, scanning electron microscope(SEM) ,electon probe and X-rays diffraction. The obtained results indicate that the weld deposited coating of boronic stainless steel has better resistance to cavitation eroion, while weld deposited coating of WC ceramics is a better barrier to erosion and abrasion. Forthermore,the material failure from erosion and abrasion is resulted from the combining actions of the minus pressure because of bubble crumbling and the tangential componental force caused by the dashing of silt granular.

In order to enlarge the field of application, reduce the cost of software rejuvenation and improve software availability and reliability,the adaptive software rejuvenation with fine rejuvenation granularity of object-oriented software system would be put forward. Based on the characteristics of the component and coupling relation between the components of the system, this paper determines the finest rejuvenation granularity, analyzes the degree of the coupling relation,sets down a method to calculate the restart dependence and its degree of the components,so that determines the restart reachable set of each component and gets the restart gather of the components at every granularity,and finally sets down and models the adaptive nested software rejuvenation policy. So executing intelligent software rejuvenation at fine rejuvenation granularity in the object-oriented software system can be supported.

Strategic Study of CAE 2010, Volume 12, Issue 4, Pages 90-94
The paper summarized and evaluated asphalt mixture anti-shear test method, anti-shear mechanism and the anti-shear design reasearch recently. The analysis and evaluation of 9 test methods is helpful for related personnel to choose these test methods appropriately. The properties of asphalt grout, anti-shear strength between asphalt and aggregate interface, and interlocking of aggregates, jointly decide HMA (hot mix asphalt) anti-shear strength and are the orientation to improve HMA anti-shear properties. Further researches are needed before anti-shear design is used in engineering to solve the problems such as the determination of relevant coefficient in tolerable shear stress test method and calibration of rutting prediction models based on HMA anti-shear behaviors.

Strategic Study of CAE 2012, Volume 14, Issue 1, Pages 31-36
This paper analyzes DX single pile with 2 bearing plates on its resistance of uplift load by numerical analysis method. The parameters for analysis are drawn from lab test and verified by large scale loading test of DX piles. The Q-s curve and axial force of DX pile are obtained,and the conclusions based on the analysis are drawn.The uplift bearing capacity of DX single pile is about more than twice larger than that of the normal single pile and its bearing plates work out from the upper to the lower order, while when the bearing capacity reaches certain level, the lower plate will play a more important role.

The structure, reproduction, replication and transcription of RNA viruses were introduced. Antivirus strategies including design of anti - SARS drugs, RNA interference, DNA vaccine delivery system, modulation of interaction of envelop glycoprotein with glycosanminoglycan derivatives or analogues, natural herbal medicine and alveolus tissue engineering were reviewed. These examples imply the interactions of RNA viruses with proteins, DNA, and polysaccharides. Nowadays biomaterials matrixes or vectors are developing toward the third generation, i.e. cell or/and activated ones. It is sure that biomaterials will play a crucial role in fighting against SARS viruses and the like.

The most common approaches to prevent and treat graft-versus-host disease (GVHD) are intended to deplete or suppress the T cells capable of mediating or supporting alloresponses; however, this renders the recipients functionally T cell deficient and hence highly susceptible to infections and tumor recurrence. Depletion is often accomplished through the use of broadly reactive antibodies, while functional impairment is typically achieved by pharmacological agents that require long-term administration (usually six months or more), have significant side effects, and may not result in tolerance (i.e., nonresponsiveness) of donor T cells to conditioning regimen-resistant host alloantigen-bearing cells. As our knowledge of immune system homeostasis has increased, cell populations with immune regulatory function have been identified and characterized. Although such cell populations are typically present in low frequencies, methods to isolate and expand these cells have permitted their supplementation to the donor graft or infusion late post-transplant in order to stifle GVHD. This review discusses the biology and preclinical proof of concept of GVHD models, along with GVHD outcomes that focus exclusively on immune regulatory cell therapies that have progressed to clinical testing.

Discussion on formula for anti pull bearing capacity of DX pile
Yuan Xiyu,He Dexin,Chen Lihong
Strategic Study of CAE 2012, Volume 14, Issue 1, Pages 69-73
When the DX-pile is under uplift load, the pile-soil interaction consists of pile shaft resistance and uplift resistance provided by the bells which effectively raises the uplift-pile ultimate bearing capacity. The friction resistance along pile shaft friction has been study well and has lots of results, but the problem of calculating the resistance of bell is still under studied which is the key to DX-pile uplift capacity. This paper calculates the bearing capacity of DX-pile and compares it with the measured value on the basis of a project to discuss and study these calculation methods, and a new method of calculation is also proposed.
