＜正＞ The present paper deals with satellite formation keeping control problem. A normalization linear equation of satellite relative motion including J2.perturbation is derived. Then a sliding mode control with matching uncertainty and disturbance is introduced, such that the modeling error and disturbance is included in the control design. A simulation with nonlinear dynamics and perturbations is made to establish the robustness and performance of the controller.

Background Previous investigations into the effect of dietary forage on calf performance have been inconsistent,and there is a paucity of information exploring the effect of age on the growth performance and rumination of ***-four female Holstein calves(41.5±4.2.kg)were enrolled at birth,a subset of the calves were fed calf starter only(CON,n=2.)while the rest(n=63)were classified into three treatment groups:the early(EHAY,n=2.,5.1±0.8 d),the middle(MHAY,n=2.,7.9±0.8 d)and the late(LHAY,n=16,12.1±1.4 d)hay *** short-term effect of the age at first forage consump-tion(AFF)on calves’feed intake was monitored until d *** addition,the long-term effects of AFF on body weight,structural growth and rumination behavior were recorded until d *** samples were collected on d 1,7,35,84 and 196 to ana-lyze the rumen fermentation,while fecal samples were collected from d 78 to 84 to estimate digestibility *** Treatment had no effect on feed ***,the EHAY calves tended to have lower BW and ADG compared to LHAY and CON *** total-tract apparent digestibility parameters and digestible nutrients intake were significantly lower in EHAY calves compared with CON and LHAY *** in the EHAY group tended to begin ruminating ealier,while CON calves were the latest(12.3 vs.15.5 days of age).A treatment and time interaction was present for rumination time due to greater rumination in calves consuming hay compared to CON calves in week 10 to 12.the differences in rumination disappeared afterwards,no long-lasting significant differences in the rumina-tion and rumen fermentation parameters were found between *** In conclusion,this study showed that hay consumption earlier in life(in the first week,around 5 days of life)could negatively affect the growth of the calf in the short and long *** to consuming hay from the second week(around 12.days of life)or feeding concentrate only without hay,starting

Dear Editor,Maintenance of cardiomyocyte(CM)homeostasis is essential for normal heart ***-term imbalance in heart homeostasis could elicit irreversible adaptive change in cell structure and function and tissue architecture,exemplified as cardiac hyper-trophy and fibrosis,and eventually develop into heart failure(Shiojima et al.,2.05).Therefore,identifying new genes and path-ways regulating CM homeostasis may help better understand the cause of cardiac hypertrophy.

The cellular structured titanium alloys have attracted significant attention for implants because of their lower Young’s modulus,which is comparable to human bone and has the capability of providing space for bone tissue ***,there is a gap in the knowledge in regard to the relationship between the pore characteristics and the electrochemical performance of open-cellular structured titanium *** this study,we elucidate the influence of pore characteristics on the electrochemical performance of open-cellular structured Ti-6Al-4V alloys produced by electron beam melting(EBM).Intriguingly,the passive film formed on cellular structured Ti-6Al-4V alloy with a larger pore size was more stable and protective,and the corrosion performance was superior compared to the samples with a smaller pore size in phosphate buffered saline(PBS),mainly because of relatively smaller exposed surface area and unlimited flow of ***,in acidic PBS containing fluoride ions,the pore characteristics did not play an important role in the corrosion *** was considered that the protective film breaks down such that the corrosion performance of cellular structured alloys was comparable to each other in this harsh environment.
