In searching of differentially expressed genes in human uterine leiomyomas, differential display was used with twelve pairs of primers to compare human uterine leiomyomas with matched myometrium. False positives were eliminated by reverse Northern analysis. Positives were confirmed by Northern blot analysis. RESULTS: [1] Four of 69 cDNA fragments (3 up-regulated named L1, L2 and L3 and 1 down-regulated named Mi in leiomyoma) were confirmed by Northern analysis. [2] Sequence comparison and Northern analysis proved that Li is exactly the human ribosomal protein Si9. [3] It was present ubiquitously in i3 tissues tested but in various levels and even in different size. [4] Li was highly expressed in parotidean cystadenocarcinoma, pancreatic cancer and breast cancer examined. [5] No mutations have been found in human uterine leiomyomas (n=6). CONCLUSIONS: hRPSi9 overexpression might be a universal signal in rapid cell growth tissues.

A model reduction approach for discrete-time linear time-variant systems with delayed inputs

引用

Science China(Information Sciences) 2024年第4期67卷 197-217页

作者： Ai-Guo WU Guang-Ren duan yu WANG Jie ZHANG School of Mechanical Engineering and Automation Harbin Institute of Technology(Shenzhen) HIT Wuhu Robot Technology Research Institute Center for Control Science and Technology Southern University of Science and Technology

A model reduction approach is presented for discrete-time linear time-variant input-delayed systems. According to this proposed approach, a dynamical variable is constructed by taking advantage of the current state and historical information of input. It is revealed that the behavior of this dynamical variable is governed by a discrete-time linear delay-free system. It is worth noting that the presented variable transformation does not require the system matrix to be invertible. Based on the reduced delay-free models,stabilizing control laws can be easily obtained for the original delayed system. For the case with a single input delay, the constructed variable is an exact prediction for the future state, and thus the stabilizing control law could be designed by replacing the future state with its prediction. Finally, three discrete-time periodic systems with delayed input are employed to illustrate how to utilize the presented model reduction approaches.
