Science and innovation diplomacy is at a crossroad-facing the need for enhanced cooperation to tackle global challenges and in a more complex geopolitical *** on“learning-by-doing”and“learningby-experimenting”as well as focusing on future development needs and opportunities,the science and innovation diplomacy practices of“Nordic+”countries,i.e.,Denmark,Finland,Sweden and the netherlands,in China are presented in the *** common strategic insights can be summarized as:1)a new policy narrative on“co-opetition”,2)a balanced approach and a long-term and future-oriented perspective on“coopetition”and 3)more agile,targeted and impact-oriented instruments and partnerships for“co-opetition”.Concrete suggestions for the future development include:1)a deepened understanding of how science and innovation are inter-connected with strategic and economic interests of countries and continents,2)publicly funded schemes and instruments for engaging Nordic multinationals and deepening science-industry-policy collaborative efforts,3)systematic methods through combining evidence-based and future-oriented analyses and 4)skill-and capacity development for identifying,preventing and mitigating multifaceted risks in *** such contexts,the implementation of EU’s mission-driven innovation and the twin-transition,*** sustainability transition and digital transition,can open up new opportunities for the future cooperation.

Fusarium ear rot(FER)is a destructive maize fungal disease *** this study,three tropical maize populations consisting of 874 inbred lines were used to perform genomewide association study(GWAS)and genomic prediction(GP)analyses of FER *** phenotypic variation and high heritability for FER were observed,although it was highly influenced by large genotype-by-environment *** the 874 inbred lines,GWAS with general linear model(GLM)identified 3034 single-nucleotide polymorphisms(SNPs)significantly associated with FER resistance at the P-value threshold of 1×10^(-5),the average phenotypic variation explained(PVE)by these associations was 3%with a range from 2.33%to 6.92%,and 49 of these associations had PVE values greater than 5%.The GWAS analysis with mixed linear model(MLM)identified 19 significantly associated SNPs at the P-value threshold of 1×10^(-4),the average PVE of these associations was 1.60%with a range from 1.39%to 2.04%.Within each of the three populations,the number of significantly associated SNPs identified by GLM and MLM ranged from 25 to 41,and from 5 to 22,*** SNP associations across populations were rare.A few stable genomic regions conferring FER resistance were identified,which located in bins 3.04/05,7.02/04,9.00/01,9.04,9.06/07,and 10.03/*** genomic regions in bins 9.00/01 and 9.04 are *** produced moderate accuracies with genome-wide markers,and relatively high accuracies with SNP associations detected from *** prediction accuracies were observed when the training and validation sets were closely *** results implied that FER resistance in maize is controlled by minor QTL with small effects,and highly influenced by the genetic background of the populations *** selection(GS)by incorporating SNP associations detected from GWAS is a promising tool for improving FER resistance in maize.

Using data taken at 29 center-of-mass energies between 4.16 and 4.70 GeV with the BESⅢdetector at the Beijing Electron Positron Collider corresponding to a total integrated luminosity of approximately 18.8 fb^(-1),the process e^(+)e^(-)→pppñπ+*** observed for the first time with a statistical significance of 11.5σ.The average Born cross sections in the energy ranges of(4.160,4.380)GeV,(4.400,4.600)GeV and(4.610,4.700)GeV are measured to be(21.5±5.7±1.2)fb,(46.3±10.6±2.5)fb and(59.0±9.4±3.2)fb,respectively,where the first uncertainties are statistical and the second are *** line shapes of the pñ and ppπ^(-)invariant mass spectra are consistent with phase space distributions,indicating that no hexaquark or di-baryon state is observed.
