The expert set theory performs an important part in making decisions. It can successfully convey the opinions of every expert since it includes several experts. In this study, generalizations and soft expert sets are combined. First, the generalized soft expert set notion is presented, then follows the definition of operation approaches and characteristics as the complement, union, intersection, AND and OR. The application of the generalized soft expert set concept to decision issues is then presented with an example. The study also introduces the idea of a generalized soft expert matrix and demonstrates how it may be used to solve decision-making issues. The most striking aspect of this paper is to present the concepts of generalized soft expert sets and generalized soft expert matrices and to apply them to the same decision-making scenario.

OBJECTIVE: To investigate the therapeutic efficacy of Tiaobu Feishen formulae(TBFS) on cigarette smoke-induced inflammation in vitro using lipopolysaccharide(LPS)-induced and cigarette smoke extract(CSE)-induced NCI-H292 ***: We evaluated the inhibitory effects of Bufei Jianpi formula(BJF), Bufei Yishen formula(BYF), and Yiqi Zishen formula(YZF) on the expressions of inflammatory cytokines including tumor necrosis factor(TNF)-α and interleukin(IL)-8, matrix metalloproteinase(MMP)-9, tissue inhibitor of matrix metalloprotease(TIMP)-1, and superoxide dismutase(SOD) in H292 cells stimulated with LPS or CSE. Their related transcription factors and signaling pathways were also ***: BJF, BYF, and YZF significantly inhibited the LPS-or CSE-induced expressions of TNF-α, IL-8,MMP-9, TIMP-1, and SOD in H292 cells, and suppressed the activation of transcription factors including nuclear transcription factor(NF)-κB, activator protein(AP)-1, and signal transducers and activators of transcription(STAT) 3 and their corresponding pathways, including NF-κB, mitogen-activated protein kinase(MAPK), STAT3, and peroxisome proliferator-activated receptor(PPAR).CONCLUSION: BJF, BYF, and YZF effectively suppressed inflammatory responses, protease-antiprotease imbalance, and oxidative stress induced by LPS and CSE, an effect that was closely associated with the inhibition of the NF-κB, MAPK, STAT3, and PPAR pathways.

In this paper, a block coordinate descent method is developed to solve a linearly constrained separable convex optimization problem. The proposed method divides the decision variable into a few blocks based on certain rules. Then the candidate solution is iteratively obtained by updating one block at each iteration. The problem, whether or not there are overlapping regions between two immediately adjacent blocks, is investigated. The global convergence of the proposed method is established under some suitable assumptions. Numerical results show that the proposed method is effective compared with some ＂full-type＂ methods.

空天地一体化网络(SAGIN)通过提高地面网络的资源利用率可以有效满足多种业务类型的通信需求,然而忽略了系统的自适应能力和鲁棒性及不同用户的服务质量(QoS)。针对这一问题,该文提出在空天地一体化网络架构下,面向城区和郊区通信的深度强化学习(DRL)资源分配算法。基于第3代合作伙伴计划(3GPP)标准中定义的用户参考信号接收功率(RSRP),考虑地面同频干扰情况,以不同域中基站的时频资源作为约束条件,构建了最大化系统用户的下行吞吐量优化问题。利用深度Q网络(DQN)算法求解该优化问题时,定义了能够综合考虑用户服务质量需求、系统自适应能力及系统鲁棒性的奖励函数。仿真结果表明,综合考虑无人驾驶汽车,沉浸式服务及普通移动终端通信业务需求时,表征系统性能的奖励函数值在2 000次迭代下,相较于贪婪算法提升了39.1%;对于无人驾驶汽车业务,利用DQN算法进行资源分配后,相比于贪婪算法,丢包数平均下降38.07%,时延下降了6.05%。

验证性因子分析显示,中高层管理人员评价的高管团队内聚力不能有效区分社会内聚力和任务内聚力,而企业家评价的高管团队内聚力则较好区分了内聚力的两个维度。这种评价差异的原因可能主要由两个群体所处的位置、他们工作性质的不同等原因造成的。企业家评价的高管团队内聚力两个维度中,社会内聚力维度对家族企业继承绩效的预测力更强,对客观继承绩效和主观继承绩效都有显著的影响。任务内聚力维度对主观继承绩效有较大显著影响,对客观继承绩效影响较小。这与过去绝大多数关于内聚力绩效关系研究的成果正好相反。这一方面可能与高管团队更多战略执行决策,较少操作性的任务性质有关,另一方面也许正说明了在集体主义文化浓厚的中国,对处于交接班这一重大变革时期的家族企业来说,如何确保高管团队内部的和谐、心理相容,实现权力的平稳过渡对家族企业继承的成功是最重要的。
