For full-state constrained nonlinear systems with input saturation, this article studies the output-feedback tracking control under the condition that the states and external disturbances are both unmeasurable. A novel composite observer consisting of state observer and disturbance observer is designed to deal with the unmeasurable states and disturbances simultaneously. Distinct from the related literature, an auxiliary system with approximate coordinate transformation is used to attenuate the effects generated by input saturation. Th

Results were analyzed using SPSS version 23.0 software. RESULTS There were statistically significant differences in ERCC2 Lys751Gln rs13181 polymorphism variants GG colon and GT in the colon control and GG,TTprostate cancer groups when compared with the control group.. GG variant of XRCC2 Arg188 rs3218536 was higher in the gastric patient group. AG variant of XRCC2 Arg188 rs3218536 was higher in gastric control group Conclusion The results of the present study demonstrate that ERC22 Lys751Gln polymorphisms may be associated with the d
