Soybean cyst nematode(SCN)is a highly destructive *** soybean host genome harbors at least two major genes for resistance(rhg1 and Rhg4),as well as a minor locus(SCN3-11).In the present study,a splicing site in GmSNAP11,the potential causal gene of SCN3-11,was identified by comparison of the GmSNAP11 cDNA sequences generated from resistant and susceptible soybean *** sequence information was used to design a codominant CAPS marker,GmSNAP11-2565,which was used to genotype a panel of 209 soybean accessions varying with respect to SCN *** of the effect of the haplotypes formed by GmSNAP11-2565 and another large-effect(nonsynonymous)locus,GmSNAP11-2307,previously identified in GmSNAP11,revealed linkage disequilibrium(P<0.0001)between the two loci,suggesting that GmSNAP11-2565 could be used as a marker for ***11-2565 was accordingly used,along with established markers for GmSNAP18(rhg1)and GmSHMT(Rhg4),to characterize the panel *** mean SCN female index of accessions carrying only the GmSNAP11 allele associated with resistance(20.3%)was higher than that associated with accessions carrying alleles for resistance at both GmSNAP11 and GmSNAP18(12.4%),while the index for accessions carrying alleles for resistance at all of GmSNAP11,GmSNAP18,and GmSHMT was very low(1.9%).Selection on all three markers was effective for maintaining a high level of resistance to SCN race 3.

This paper analyses the synchronization problem of switched cellular neural networks. The admissible edge-dependent average dwell time method is used to design switching signals. By virtue of the multiple Lyapunov function technology and Newton-leibniz formula, a sufficient condition is established to guarantee the exponential synchronization of switched cellular neural networks. Finally, a numerical example is employed to verify the effectiveness of proposed methods.

Mathematical Infinity and Medium Logic （I） --Logical-mathematical Interpretation of leibniz＇s Secant and Tangent Lines Problem in Medium Logic

From the perspective of potential infinity (poi) and actual infinity, Ref [4] has confirmed that poi and aci are in 'unmediated opposition' (P,﹁P ) whether in ZFC or not; it has further been proved that the manners in which a variable infinitely approaches its limit also satisfy the law of intermediate exclusion. With these results as theoretical bases, this paper attempts to provide an accurate and strict logical-mathematical interpretation of the incompatibility of leibniz's secant and tangent lines in the medium logic system from the perspective of logical mathematics.

Abstract： Ref [5] provides a logical-mathematical explanation of the incompatibility ofleibniz＇s secant and tangent lines in medium logic. However, the expression （＊）（△y/△x） ismeaningful and dy/dx is the tangent slope） derived from ⑦ and ⑧ in §4 of Ref [5] is unimaginablewithin the framework of two-valued logic, why shouldn＇t the same conflicting concluslon be reached in the medium logic calculus？ This paper has subjected these questions to careful logical analysis, and approached them from the perspective of logical mathematics. As the two approaches have led to the identical conclusion, the paper thereby rigorously and thoroughlv answers these questions.
