Let g be a finite dimensional complex simple Lie algebra with Cartan subalgebraη.Then C[η]has a g-module structure if and only if g is of type A or of type C;this is called the polynomial module of rank one,In the quantum version,the rank one polynomial modules over U_(q)(sl_(2))have been *** this paper,we prove that the quantum group U_(q)(sl_(3))has no rank one polynomial module.

Paired amphipathic helix protein (SIN3B) is a transcription corepressor for many genes. Here we show a different regulation mechanism of integrin aV gene expression by SIN3B in human hepatocellular carcinoma (HCC). We first observed a close relationship between Integrin aV and SIN3B expressions in HCC patients and tumor cell lines with different metastatic potentials. Overexpression of SIN3B significantly accelerated the cell migration rate of SMMC-7721, but failed when integrin αV expression was silenced. Interestingly, SIN3B stimulated integrin aV subunit promoter activity only in the presence of sulfatide. Importantly, SIN3B was identified in the complex with sulfatide by mass spectrometry. Fat blot assay indicated that SIN3B specifically interacted with sulfatide. Molecular modeling suggested that sulfatide induced the conformational change of SIN3B from compacted α-helices to a relaxed β-sheet in PAH2 domain. The data of immunoprecipitation and ChIP assay indicated that altered SIN3B lost the binding affinity with MAD1 and HDAC2, which reduced the recruitment of HDAC2 on integrin aV gene promoter and prevented the deacetylation of the histone 3. In conclusion, this study demonstrated that SIN3B promoted the transcriptional activation of the integrin αV subunit gene promoter by reducing interaction with HDAC2.

Carbon dioxide (CO_(2)) is a principal greenhouse gas with a substantial impact on global climate change. The photocatalytic reduction of CO_(2) represents an economically viable and environmentally benign approach. This technique involves the catalysis of the reaction between CO_(2) and epoxides under photocatalytic conditions to yield cyclic carbonates. Notably, this process has garnered significant attention due to its high atomic efficiency and alignment with green chemistry principles. Increasingly, photocatalysts are employed to facilitate the synthesis of cyclic carbonates, demonstrating outstanding performance even under natural light. This review evaluates the current state of research on the photocatalytic cycloaddition of CO_(2) with epoxides, analyzes the reaction mechanism and key influencing factors, and provides a comparative summary of the photocatalysts developed in this domain. Additionally, this paper underscores the significance of the reaction devices. The paper explores reaction devices with potential applications for photocatalytic CO_(2) and epoxides and envisions future integrations of CO_(2) photocatalytic cycloaddition reactions with advanced reaction devices for practical applications in this area.

多目标多任务进化优化是多目标优化的一个重要研究方向,通过跨任务共享有益信息以同时解决多个相关任务的优化问题。然而,现有多目标多任务进化优化研究存在相似任务匹配准确度低、缺少对知识迁移的动态控制等问题。为提高多目标多任务进化优化算法的优化效果,引入相似性动态指标和迁移概率动态调整机制,提出自适应迁移的分解多目标多任务进化算法。为了给目标任务子问题匹配关联度最高的迁移源,同时考虑种群的当前分布以及种群的进化方向2个指标,设计一种基于种群静态和动态特征相结合的迁移源匹配策略。为了合理地控制任务间的信息传递,提出基于种群进化状态的知识迁移概率自适应调整策略,在优化过程中根据优化任务的进化状态自适应地调整任务间的知识迁移概率,以满足优化任务在不同进化阶段对外部知识的需求。实验结果表明,相比MOEA/D、MO-MFEA、MO-MFEA-Ⅱ等算法,该算法具有较优的稳定性和收敛性,在常用的9组(18个独立任务)多目标多任务测试问题中有15个表现较优,优化率为83%。
