This paper is to provide a novel approach for the spatial aggregation of judgment matrices.The optimal aggregation method of judgment matrices based on spatial Steiner-Weber point can effectively aggregate the preference information of group members and achieve the optimization of group preference.The method comprises three key elements:The spatial mapping of the judgment matrices,the spatial optimal aggregation model of the judgment matrices,and the plant growth simulation algorithm(PGSA)is used to find the optimal aggregation points.Firstly,the judgment matrices are mapped into a set of spatial multidimensional coordinates by using spatial mapping rules.Secondly,the spatial Steiner-Weber point is used as the prototype to construct the spatial aggregation model.Thirdly,the PGSA algorithm is used to find the spatial aggregation points,whose spatial weighted Euclidean distance to all the decision makers’preference points is minimal.The optimal aggregation matrix is composed of these optimal aggregation points,which can accurately reflect the decision maker's comprehensive opinions.Finally,the effectiveness and rationality of this method are verified by comparing with the classical group preference aggregation methods.

目前许多学者认为,川渝安岳———大足地区分布着的一批佛教石刻造像是四川密宗造像,简称“川密”造像;其中最醒目的题材是柳本尊行化图,其核心区域就是大足宝顶山的大、小佛湾,教主是唐末五代的柳本尊、南宋的赵本尊。但从宝顶山石刻的内容看,更多是华严、禅宗、净土等雕刻,柳本尊的立雪断臂等修行方式也来自禅宗,铭文中“六代祖师传密印”也是指禅宗六祖。而且晚唐至宋,正是禅宗发展壮大、合并其它宗派的时期,立雪、断臂类修行故事也正流行,柳本尊正是活动在这个时间范围内。从图像内容、经文、铭文等各方面看,有理由认为柳本尊所传之法实为融合了华严、净土等思想的禅宗,赵智凤教派其实继自禅宗;至明清时期复兴之后,仍为禅宗。

This paper presents a neighborhood optimal trajectory online correction algorithm considering terminal time variation,and investigates its application range.Firstly,the motion model of midcourse guidance is established,and the online trajectory correction-regenerating strategy is introduced.Secondly,based on the neighborhood optimal control theory,a neighborhood optimal trajectory online correction algorithm considering the terminal time variation is proposed by adding the consideration of terminal time variation to the traditional neighborhood optimal trajectory correction method.Thirdly,the Monte Carlo simulation method is used to analyze the application range of the algorithm,which provides a basis for the division of application domain of the online correction algorithm and the online regeneration algorithm of midcourse guidance trajectory.Finally,the simulation results show that the algorithm has high real-time performance,and the online correction trajectory can meet the requirements of terminal constraint change.The application range of the algorithm is obtained through Monte Carlo simulation.

In the field of antitumor drug development,it is common to see paired images of cultured cancer cells:one mocktreated,and the other subjected to a small molecular drug that leads to cell death or growth suppression(Figure 1).One’s common perception is that an inhibitor is at work to inactivate a critical factor or pathway essential for

The complexity measures of chaotic or periodic signals are perpetual topics of interest to data scientists. This work adheres to the framework of the traditional 0-1 test for chaos and replaces sine and cosine functions by modified sign functions. The compressive mapping rules chosen are one-threshold of three-value or three-threshold of five-value. In new criteria for chaos in forms of the 3s plot and Ks metric compared with 0-1 test results, the periodic state of data features a short beeline instead of a big ring in the pq plot and signs the nearest zero mark, while the chaotic state signs a simple curve instead of a random-walking shape in the pq plot, and shows the nearest one mark. By computing the Lorenz equation evolution under the contrast tests of the Poincare section and Lyapunov index, we visualize a new chaoscriteria design in symbolic dynamics and data compression principles, and our work may lay the foundation for further expressing the chaotic appearance of novel signals deep into future brainets.

A graph is 1-planar if it can be drawn on the Euclidean plane so that each edge is crossed by at most one other edge.A proper vertex k-coloring of a graph G is defined as a vertex coloring from a set of k colors such that no two adjacent vertices have the same color.A graph that can be assigned a proper k-coloring is k-colorable.A cycle is a path of edges and vertices wherein a vertex is reachable from itself.A cycle contains k vertices and k edges is a k-cycle.In this paper,it is proved that 1-planar graphs without 4-cycles or 5-cycles are 5-colorable.

To survive,animals must process aversive or stressful events quickly,and evaluate and store the related information.Accumulating neural circuity studies have identified key brain nuclei,such as the amygdala,lateral habenula (LHb),periaqueductal grey (PAG),ventromedial hypothalamic nucleus,hippocampus,among others,in the processing of negative experiences [1,2].Yet more work is needed to determine how these brain structures coordinate with each other in coping with such experiences.

Let BE be a bounded symmetric domain realized as the unit open ball of JB^(*)-triples.The authors will characterize the bounded weighted composition operator from the Bloch space B(BE)to weighted Hardy space Hv∞in terms of Kobayashi distance.The authors also give a sufficient condition for the compactness,and also give the upper bound of its essential norm.As a corollary,they show that the boundedness and compactness are equivalent for composition operator fromB(BE)to H∞(BE),when is a finite dimension JB^(*)-triple.Finally,they show the boundedness and compactness of weighted composition operators from B(BE)to Hv,0∞(BE)are equivalent when is a finite dimension JB^(*)-triple.

Anti-CD 19 chimeric antigen receptor(CAR)T cell therapy has shown impressive efficacy in treating B-cell malignancies.A single-center phase I dose-escalation study was conducted to evaluate the safety and efficacy of T cells transduced with CBM.CD19 CAR,a second-generation anti-CD19 CAR bearing 4-1BB costimulatory molecule,for the treatment of patients with refractory diffuse large B-cell lymphoma(DLBCL).Ten heavily treated patients with refractory DLBCL were given CBM.CD19 CAR-T cell(C-CAR011)treatment.The overall response rate was 20%and 50%at 4 and 12 weeks after the infusion of C-CAR011,respectively,and the disease control rate was 60%at 12 weeks after infusion.Treatment-emergent adverse events occurred in all patients.The incidence of cytokine release syndrome in all grades and grade^3 was 90%and 0,respectively,which is consistent with the safety profile of axicabtagene ciloleucel and tisagenlecleucel.Neurotoxicity or other dose-limiting toxicides was not observed in any dose cohort of C-CAR011 therapy.Antitumor efficacy was apparent across dose cohorts.Therefore,C-CAR011 is a safe and effective therapeutic option for Chinese patients with refractory DLBCL,and further large-scale clinical trials are warranted.
