有容量车辆路径问题是组合优化问题中比较热门的问题,它属于经典的NP-hard问题并且时间复杂度高.本文提出了一种基于策略梯度的超启发算法,将强化学习中的确定性策略梯度算法引入到超启发算法的高层策略中的底层算法选择策略,确定性策略梯度算法采用Actor-Critic框架,另外为了能够在后续计算和神经网络参数更新中引用历史经验数据,在确定性策略梯度算法中设计了经验池用于存储状态转移数据.在超启发算法解的接受准则方面,文中通过实验对比了3种接受准则的效果,最终选择了自适应接受准则作为高层策略中解的接受准则.通过对有容量车辆路径问题标准算例的计算,并将求解结果与其他算法对比,验证了所提算法在该问题求解上的有效性和稳定性.

The Navier-Stokes-α equations subject to the periodic boundary conditions are considered. Analyticity in time for a class of solutions taking values in a Gevrey class of functions is proven. Exponential decay of the spatial Fourier spectrum for the analytic solutions and the lower bounds on the rate defined by the exponential decay are also obtained.

Feedback processing in the primate brain and in AI systems

The primate brain and artificial intelligence(AI) can both be conceptualized as information processing systems, each with its own distinct biological and computational architectures. While there are parallels between them, their respective structural and functional connections show significant differences. In this paper, we examine the central role of feedback processing in both the primate brain and AI systems, which has been shown to be crucial in shaping neural processing. By reviewing the key features of feedback processes in the primate brain, which allows the brain to incorporate prior knowledge, contextual information, and taskdemands into early-stage processing, we highlight the divergence in goals and functions between biological and AI *** these differences is crucial for elucidating the cognitive capabilities of the primate brain and for addressing computational challenges in AI. In advocating “Cognition-Inspired-Computation”, we suggest that integrating insights from feedback processing in the primate brain into AI research will offer potentially significant improvements for the advancement of AI systems.

Circular RNAs(circRNAs)are ideal biomarkers of oral squamous cell carcinoma(OSCC)because of their highly stable closed-loop structure,and they can act as microRNA(miRNA)sponges to regulate OSCC *** analyzing clinical samples,we identified circCPNE1,a dysregulated circRNA in OSCC,and its expression level was negatively correlated with the clinical stage of OSCC ***-of-function assays revealed the tumor-suppressive effect of circCPNE1,which was then identified as a miR-330-3p ***-330-3p was recognized as a tumor promoter in multiple studies,consistent with our finding that it could promote the proliferation,migration,and invasion of OSCC *** results indicated that selective inhibition of miR-330-3p could be an effective strategy to inhibit OSCC ***,we designed cationic polylysine-cisplatin prodrugs to deliver antagomiR-330-3p(a miRNA inhibitory analog)via electrostatic interactions to form PP@miR nanoparticles(NPs).Paratumoral administration results revealed that PP@miR NPs effectively inhibited subcutaneous tumor progression and achieved partial tumor elimination(2/5),which confirmed the critical role of miR-330-3p in OSCC *** findings provide a new perspective for the development of OSCC treatments.

目的:探究酒精性肝硬化(ALC)患者血脂水平与Child-Pugh分级之间的关系。方法:选取2020年8月至2022年2月在首都医科大学附属北京地坛医院住院的ALC患者348例,其中Child-Pugh A+B级患者共有245例,Child-Pugh C级患者103例,记录患者的性别、年龄、实验室指标;通过单因素和多因素二元Logistic回归得出判断Child-Pugh C级的独立危险因素;绘制受试者工作特征曲线(ROC),得出曲线下面积(AUC)来评估诊断价值,并根据约登指数计算cut-off值。结果:与Child-Pugh A+B级患者相比,Child-Pugh C级患者WBC、AST、TBil、PT、INR水平都显著高于前者,而RBC、Hgb、PLT、Alb均低于前者;TC、TG、HDL-C、LDL-C水平低于前者,尤其是HDL-C水平降低更为明显。以所属的Child-Pugh等级作为因变量,通过单因素和多因素Logistic回归显示,年龄(OR=0.932,95%CI=0.899~0.966,P<0.001),WBC(OR=1.196,95%CI=1.053~1.360,P=0.006),PLT(OR=0.989,95%CI=0.982~0.995,P=0.001),CHE(OR=0.999,95%CI=0.998~0.999,P<0.001),HDL-C(OR=0.252,95%CI=0.082~0.779,P=0.017)是Child-Pugh C级的独立危险因素。进一步绘制HDL-C的ROC曲线,得出AUC为0.783,显著高于TC、TG、LDL-C的AUC,分别为0.611、0.550、0.623,显示了HDL-C较好的诊断价值;并根据约登指数得出HDL-C的cut-off值是0.645 mmol/L。结论:ALC患者的HDL-C水平对Child-Pugh分级有一定的参考价值。
