After a whistleblower exposed a large-scale fraud,there has been a surge in retractions,affecting scientific integrity and attracting extensive attention from various stakeholders.1,2 Countries,institutes,and journals are among the entities receiving special attention.3,4 However,our understanding of the actual prevalence of misconduct across disciplines and topics remains *** studies of academic misconduct have primarily focused on biomedical and life sciences,3 but have paid little attention to the broader scientific fields.

利用ANSYS/LS-DYNA软件建立了混凝土钢丝骨架夹芯墙有限元模型,分析了单独冲击波作用、单独破片作用及二者复合作用下混凝土钢丝骨架夹芯墙位移响应的差异,探究了不同混凝土轴心抗压强度、钢丝骨架屈服强度、聚苯乙烯泡沫密度、斜插丝角度及布置方式、两侧混凝土及泡沫厚度、炸药比例距离和高度以及破片尺寸对混凝土钢丝骨架夹芯墙位移响应的影响。通过试验进行了对比验证,结果表明:建模方式是可靠的;单独冲击波作用下墙体的位移要大于单独破片作用及二者复合作用下的位移,但是在二者复合作用下墙体会产生更严重的损伤破坏;随着混凝土轴心抗压强度以及两侧混凝土厚度的提升,结构抗爆性能增强;钢丝骨架屈服强度及聚苯乙烯泡沫密度对结构抗爆性能的影响微弱;不同斜插丝角度及布置方式对结构抗爆性能影响较大;炸药高度位置对墙体损伤影响不大;当炸药比例距离一定时炸药量越大墙体损伤越严重;从墙体损伤角度分析时破片尺寸越大墙体损伤越严重。

针对传统基于能量收集的全双工认知多输入多输出(MIMO)系统忽略自干扰对提高能量利用率的作用问题,建立了基于全双工MIMO的认知中继网络,通过能量收集技术进行自干扰收集.研究了系统能量效率最大化问题,在满足中继发送功率限制等约束条件下,对传输信号协方差和功率划分因子进行联合优化.利用半定松弛算法将系统优化问题转化成凸优化问题,并结合注水功率算法分析得到最优解.仿真结果表明:与传统自干扰消除模式相比,所提方案在保证系统频谱效率的同时,系统能量效率还可提高13.9%;在自干扰收集模式下,与系统容量最大化方案相比,所提方案每传输1 bit信息可降低近0.1 J的功率消耗.

针对认知无线电环境中自干扰消除问题,采用在填充式认知无线电通信机制中,次用户收发机通过全双工技术对自身干扰进行能量捕获,并推导出在安全速率、能量收集和发送功率等约束条件下的安全能量效率.利用基于泰勒级数扩展法和拉格朗日对偶分解法的迭代算法,对功率划分因子和传输协方差矩阵进行联合优化,以得到最大化安全能量效率的最优解.仿真结果表明:基于安全能效最大化的方案在低发送功率区域可实现安全能效和安全速率的同时最大化;在高功率区域,该方案在安全能效方面优于基于安全速率最大化的方案.
