Biology provides many examples of complex systems whose properties allow organisms to develop in a highly reproducible,or robust,*** such system is the growth and development of flat leaves in Arabidopsis *** mechanistically challenging process results from multiple inputs including gene interactions,cellular geometry,growth rates,and coordinated cell *** better understand how this complex genetic and cellular information controls leaf growth,we developed a mathematical model of flat leaf *** two-dimensional model describes the gene interactions in a vertex network of cells which grow and divide according to physical forces and genetic ***,the model predicts the presence of an unknown additional factor required for the formation of biologically realistic gene expression domains and iterative cell *** two-dimensional model will form the basis for future studies into robustness of adaxial-abaxial patterning.

The further improvement of methacrolein(MAL)selectivity from isobutene(IB)oxidation is crucial and *** this study,based on the typical Mo-Bi-Fe-co-k-O mixed metal oxide,the rare earth element Gd-doped,ce-doped and ceGd co-doped catalysts were prepared by co-precipitation strategy to increase the selectivity of MAL from 47.9%to 49.8%,64.2% and 68.6%,*** order to elucidate in-depth the promoting effect of ce and/or Gd,various characterizations were utilized including X-ray diffraction patterns(XRD),Raman,X-ray fluorescence spectrometry(XRF),X-ray photoelectron spectroscopy(XPS),O_(2)-temperature programmed desorption(O_(2)-TPD),H2-temperature programmed reduction(H2-TPR),cO_(2)-temperature programmed desorption(cO_(2)-TPD),IB-temperature programmed desorption(i-c4-TPD)and in-situ IB-Fourier transform infrared spectroscopy(IB-FTIR).Both ce and Gd finely regulate the bulk and surface structure of the catalyst,thus altering the redox ability,oxygen mobility and storage ability and *** with ce,Gd addition slightly regulates the variation of co^(2+)/co^(3+)redox couples,greatly enhances the interaction among the components on the catalyst,thus only increases the content of surface oxygen species and has little effect on their *** cecontaining catalyst performs stronger oxygen storage and migration ability,thus leading to the overproduction of surface Odefectspecies,which are proposed to be the active sites for the production of MAL and *** ceGd co-doped catalyst possesses the proper content of surface Odefectspecies,thus exhibits much higher MAL ***,the promoting mechanism of ce and/or Gd over IB oxidation is ***,this work is helpful for understanding the influence of rare earth elements on the structure of mixed metal oxides and the olefin selective oxidation reaction.

Dear Editor,colorectal cancer(cRc)is the third most deadly can-cer worldwide[1].The mortality of cRc has remained high due to limited treatment options for metastatic cRc(mcRc)[2].Epithelial-mesenchymal transition(EMT)is an important contributor to mcRc[2].The c-MYc proto-oncogene(MYc)-induced transcription factor AP4(TFAP4/AP4)isadriverofEMT,therebypresumablyfacil-itates mcRc[3,4].The mitogen-activated protein kinase(MAPk)/c-JunN-terminalkinase(JNk)/activatorprotein-1(AP-1)pathway has been implicated in the regulation of EMT and mcRc[5].
